3x+5=14 3x+5-5=14-5, -5 on both side 3x=9 (3x)/3=9/3, dividing by 3 on both side, so x=3
y=3x-5
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
5x + 5 = 8 -3x 5x = 3 -3x 8x = 3 x = 0.375
√(3x - 5) = 3 ∴3x - 5 = 9 ∴3x = 14 ∴x = 14/3
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
3x - 5 = 9 3x = 9 + 5 3x = 14 x = 14/3 or 4 2/3
