Solve the equation, justify
each step with an algebraic
property
50 + 3x = 7x- 2

13

Step-by-step explanation:

Step 1:

50 + 3x = 7x - 2      Equation

Step 2:

50 = 4x - 2      Subtract 3x on both sides

Step 3:

52 = 4x    Add 2 on both sides

Step 4:

x = 52 ÷ 4      Divide

x = 13

Hope This Helps :)

you will need to use the pythagorean theorem

a^2 +b^2 = c^2

where a and b are the sides of the right triangle and c is the hypotenuse
