Verified answer

-2

U first have to get the " x " by its self. So u will have 18-7= -3x -6x-7. Then take the 7 and add it to the other side which gives u 18= -9x. Divide by -9 which gives u -2

-2

x=-2

Heres why: add 6x to both sides. Add 7 to both sides. seven cacels out. so now your left with 18+9x. Subtract the 18 to other side. 9x= -18. so x=2

x= -2...

add 7 to both sides,

subtract 3x to both sides,

divide both sides by -9
