4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.
7x-1=2x+5 7x-2x=5+1 5x=6 x=6/5=1.2
8x-7 plus 2x equals 6 plus 5x plus 2?
Collect like terms: 2x + 3y + 3y - 5 - 6 2x + 6y - 11
If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
2x-11
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
2x + 1 = 6 2x = 5 x = 5/2 or 2.5
2x-5=3x+6 -5-6=3x-2x -11=x x=-11
2x+5=11 2x=6 x=3
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
X = 6
x=5
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
x=1
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
X=6
