5x + -6 = 27
Add 6 to each side: 5x = 33
Divide both sides by 5: x = 6.6
x = 6.6

If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.

5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
6x+3=27 6x=24 (subtract 3 from each side) x=4 (divide both sides by 6)
x2 + 5x + 3 = 9 x2 + 5x - 6 = 0 (x + 6)(x - 1) = 0 x = -6 or x = 1
