Step-by-step explanation:
Simplifying
2(3x + -5) = 7x + 2
Reorder the terms:
2(-5 + 3x) = 7x + 2
(-5 * 2 + 3x * 2) = 7x + 2
(-10 + 6x) = 7x + 2
Reorder the terms:
-10 + 6x = 2 + 7x
Solving
-10 + 6x = 2 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
-10 + 6x + -7x = 2 + 7x + -7x
Combine like terms: 6x + -7x = -1x
-10 + -1x = 2 + 7x + -7x
Combine like terms: 7x + -7x = 0
-10 + -1x = 2 + 0
-10 + -1x = 2
Add '10' to each side of the equation.
-10 + 10 + -1x = 2 + 10
Combine like terms: -10 + 10 = 0
0 + -1x = 2 + 10
-1x = 2 + 10
Combine like terms: 2 + 10 = 12
-1x = 12
Divide each side by '-1'.
x = -12
Simplifying
x = -12
Ответ:
13x + 10
Step-by-step explanation:
First distribute, (2)(3x) + (2)(5) + 7x
This gives you 6x + 10 + 7x
Then combine then like terms 6x + 10 + 7x
To get (6x + 7x) + (10)
And a final answer of 13x + 10 :)
