7/8x = 21 7 = 21*8x 168x = 7 x = 7/168 = 1/24

Subtract: 2x = -20Divide by 2: x = -10

9x-19=6x+2 so 3x=21 and x=7

7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7

8x=7x-7 x=-7

7/8x = 21 7 = 21*8x 168x = 7 x = 7/168 = 1/24

Subtract: 2x = -20Divide by 2: x = -10

6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8

8x - 9 = 11x + 12 8x = 11x + 21 -3x = 21 x = -7

9x-19=6x+2 so 3x=21 and x=7

7. 8x-40=2x+2 4x-20=1x+1 3x-21=0 3x=21 therefore x=7

6x-5 = 7, 6x = 7+5, 6x = 12, x = 2

Remember in algebra any operation you do to one side of the equaution and also to the other side does not affect the eqaution 8x + 7 = 2x + 49 subtract 2x from both sides 6x + 7 = 49 subtract 7 from both sides 6x = 42 divide both sides by 6 x = 7
