Wht is -3(2x-1)+8=15

Svetllana [295]

Answer:

x=- $\frac{2}{3}$

Step-by-step explanation:

subtract -3(2x-1)+8=15

-8 -8

_____________

-3(2x-1)=7

divide

$\frac{-3(2x-1)}{-3} =\frac{7}{3}$

then simplify

2x-1= $\frac{7}{3}$

add both sides

2x-1+1= $\frac{7}{3}$ +1

simplify again

2x-1+1= $\frac{7}{3}$ +1=2x= $-\frac{4}{3}$

divide by 2

2x= $-\frac{4}{3}$

-2 -2

_________

2x÷2=1

$-\frac{4}{6}divided by 2$

x=- $\frac{2}{3}$
