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}
