Question

8x = 5x - 15

What property is this
A. Distributive property
B. Addition property of equality
C. Subtraction property of equality
D. Multiplication property of equality
E. Division property of equality

Answer 1

To solve, you would need -

C. Subtraction property of equality

Isolate the x. Subtract 5x from both sides

8x (-5x) = 5x (-5x) - 15

3x = -15

Next, to isolate the x, you would need

E. Division property of equality

Divide 3 from both sides

3x/3 = -15/3

x = -5

x = -5 is your answer

hope this helps
