Question

I can tell me you’re asked to solve negative 4X -25 equals 8X +15 identify where one of them made an error

Answer 1

x = - $\frac{10}{3}$

- 4x - 25 = 8x + 15

subtract 8x from both sides

- 4x - 8x - 25 = 15

- 12x - 25 = 15

add 25 to both sides

- 12x = 15 + 25 = 40

divide both sides by - 12

x = $\frac{40}{- 12}$ = - $\frac{10}{3}$
