9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
-7 (negative 7) transpose the 9x then transpose the 6. divide both sides by 3x and your answer will be -7 =]
If: 9x+7 = 6x+25 Then: x = 6
x=-7

12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!
9x + 4 = 6 9x = 6 -4 9x = 2 x = 2/9

9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
9x-5x=4x, 7/4=1.75, x=1.75
x = 5
