Solution for 7(x+2)=4[x-(7-x)] equation:


Simplifying
7(x + 2) = 4[x + -1(7 + -1x)]

Reorder the terms:
7(2 + x) = 4[x + -1(7 + -1x)]
(2 * 7 + x * 7) = 4[x + -1(7 + -1x)]
(14 + 7x) = 4[x + -1(7 + -1x)]
14 + 7x = 4[x + (7 * -1 + -1x * -1)]
14 + 7x = 4[x + (-7 + 1x)]

Reorder the terms:
14 + 7x = 4[-7 + x + 1x]

Combine like terms: x + 1x = 2x
14 + 7x = 4[-7 + 2x]
14 + 7x = [-7 * 4 + 2x * 4]
14 + 7x = [-28 + 8x]

Solving
14 + 7x = -28 + 8x
