Question 666377
Starting with
3(2-3x) = -7 - 2(x-3)
...
Distribute the 3 and the 2
3(2) - 3(3x) = -7 - 2(x) - 2(-3)
yields
6 - 9x = -7 - 2x + 6
...
Combine like terms
{{{cross(6) - 9x - cross(6) + highlight(2x) = -7 - cross(2x) + 6 + cross(2x) - highlight(6)}}}
2x - 9x = -7 + 6 - 6
-7x = -7
...
Divide by -7
{{{cross(-7)x/cross(-7) = (-7)/-7}}}
x = 1
