Solution for y=4[x-(7-x)]-(x+1) equation: 


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

Reorder the terms:
y = 4[-7 + x + 1x] + -1(x + 1)

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

Reorder the terms:
y = -28 + 8x + -1(1 + x)
y = -28 + 8x + (1 * -1 + x * -1)
y = -28 + 8x + (-1 + -1x)

Reorder the terms:
y = -28 + -1 + 8x + -1x

Combine like terms: -28 + -1 = -29
y = -29 + 8x + -1x

Combine like terms: 8x + -1x = 7x
y = -29 + 7x

Solving
y = -29 + 7x
