Question

What value for x will make the equation true?
-3 (7x - 5) = 87 + 3x

Answer 1

x = - 3

Explanation:

Given

- 3(7x - 5) = 87 + 3x ← distribute parenthesis on left side

- 21x + 15 = 87 + 3x ( subtract 3x from both sides )

- 24x = 72 ( divide both sides by - 24 )

x = - 3

Answer 2

x=-3

Explanation:

follow the PEMDAS method then see if the 2 equation equal each other after plugging in the x.
