2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
X=44.5
2x-3y=13
3x+5 = 2x+13 3x-2x = 13-5 x = 8
2x + 1 = 13; 2x = 12; x = 6
2x plus 3y
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
2x+3y=13 3x-y=3 x=2
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-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
84
X= -8
