Question

solve -3(2x -1) = x + 10
help please

Answer 1

Expand the brackets and then isolate x.....

Answer 2

1) expand the left side
2) add 6x to both sides
3) subtract 10 from both sides
4) divide both sides by 7

Answer 3

-6x - 3 = x + 10
first step?

Answer 4

-3 = 6x + 10 for next step ? @SolomonZelman

Answer 5

you get 7x on the right side, not 6x. b/c x+6x=7x

Answer 6

So after the second step, \(\normalsize\color{red}{ \rm -3=7x+10 }\)

Answer 7

-13 = 7X

Answer 8

\(\normalsize\color{red}{ \rm 3=7x+10 }\) 3 is positive b/c (-1)*(-3)=3

Answer 9

then
\(\normalsize\color{red}{ \rm 3=7x+10 }\)
\(\normalsize\color{red}{ \rm -7=7x }\)
\(\normalsize\color{red}{ \rm -1=x }\)

Answer 10

ohhhh that makes sense
