7X = -5X + 24 add 5X to each side 12X = 24 divide both sides by 12 X = 2 check 7(2) =-5(2) + 24 14 = 14
7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
x=12
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
many solutions
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
x=6
7x-5x=8 2x=8 x=4
7X = -5X + 24 add 5X to each side 12X = 24 divide both sides by 12 X = 2 check 7(2) =-5(2) + 24 14 = 14
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
It is: 12x
7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
x=12
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
If you mean: 7x-3+5x+15 = 180 then the value of x works out as 14
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
