Solution for 3(x+3)=2[x-(7-x)] equation:


Simplifying
3(x + 3) = 2[x + -1(7 + -1x)]

Reorder the terms:
3(3 + x) = 2[x + -1(7 + -1x)]
(3 * 3 + x * 3) = 2[x + -1(7 + -1x)]
(9 + 3x) = 2[x + -1(7 + -1x)]
9 + 3x = 2[x + (7 * -1 + -1x * -1)]
9 + 3x = 2[x + (-7 + 1x)]

Reorder the terms:
9 + 3x = 2[-7 + x + 1x]

Combine like terms: x + 1x = 2x
9 + 3x = 2[-7 + 2x]
