$\large\boxed{\mathsf{-4[x] + 10 = 50}}\\\large\boxed{\rightarrow\mathsf{-4x + 10 = 50}}\\\\\large\text{SUBTRACT 10 to BOTH SIDES}\\\large\boxed{\mathsf{-4x + 10 - 10 = 50 - 10}}\\\large\text{CANCEL out: 10 - 10 because that gives you 0}\\\large\text{KEEP: 50 - 10 because it helps solve for the x-value}\\\\\large\boxed{\mathsf{50 - 10 = \bf 40}}\\\large\boxed{\mathsf{-4x = 40}}\\\\\large\text{DIVIDE -4 to BOTH SIDES}\\\large\boxed{\mathsf{\dfrac{-4x}{4}=\dfrac{40}{-4}}}$

$\large\text{CANCEL out: }\rm{\dfrac{-4}{-4}}\large\text{ because that gives you 1}\\\large\text{KEEP: }\rm{\dfrac{40}{-4}}\large\text{ because it gives you the x-value answer}\\\\\large\boxed{\mathsf{x = \dfrac{40}{-4}}}\\\\\large\text{SIMPLIFY IT AND YOU HAVE THE RESULT OF THE X! }\\\\\huge\boxed{\text{Therefore, your answer is: \textsf{x = -10}}}\huge\checkmark$

Step-by-step explanation:

$\bf \underline{Given-} \\$

$\sf{ - 4(x) + 10 = 50} \\$

$\bf \underline{To \: find-} \\$

$\sf{ \:the \: value \: of \: x = \: ? } \\$

$\bf \underline{Solution-} \\$

$\textsf{Given equation,}\\$

$\sf{ - 4(x) + 10 = 50} \\$

Now, multiply -4 from (x) to get -4x.

$\sf{ \Rightarrow \: - 4x + 10 = 50 } \\$

Now, +10 will move to RHS then it's sign will be charged -10

$\sf{ \Rightarrow \: - 4x = 50 - 10} \\$

Subtract 50 from -10 to get 40. Because 50 is greater than -10.

$\sf{ \Rightarrow \: - 4x = 40 } \\$

$\sf{ \Rightarrow \: x = \cancel\frac{ - {40}^{- 10 }}{4}} \\$

${ \: \therefore \: \underline{ \boxed{{ \sf{x = - 10.}}}}}$

EF is 4 units.

Step-by-step explanation:

It is given that the two triangles $\trianlge ABC, \triangle EDF$ are congruent to each other i.e.

$\trianlge ABC \cong \triangle EDF$

Coordinates are given as:

A(-1,1)

B(2,4)

C(3,1)

As per the property of congruence, all the corresponding sides and angles of the two triangles are equal to each other.

i.e. AB = ED

BC = DF

AC = EF

We are given with the coordinates of points A, B and C here from which we can easily calculate the side AC using the distance formula.

$Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Where (x_1,y_1), (x_2,y_2) are the coordinates of the two points whose distance is to be calculated.

So,

$AC = \sqrt{(3-(-1))^2+(1-1)^2}\\\Rightarrow AC = \sqrt{4^2}\\\Rightarrow AC = 4\ units$

Hence, AC = EF = 4 units
