2x + y = 5 so y = 5 - 2x; This gives x - 3(5 - 2x) = 13 ie x + 6x = 13 + 15 so x = 4 and y must be -3

2x + 5 = 25 2x = 20x = 10

if the number is the same: 2x + 3x = 13 5x = 13 x= 13/5

4x + 1 = 2x + 5 4x + 1 - 2x = 2x + 5 - 2x 2x + 1 = 5 2x + 1 - 1 = 5 - 1 2x = 4 2x/2 = 4/2 x = 2

6x + 3 = 2x + 5 4x = 2 x=1/2

3x+5 = 2x+13 3x-2x = 13-5 x = 8

2x + 5 = 31 2x = 31 - 5 = 26 x = 13

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.

-2x+5=13 you subtract 5 away from +5 and this cancels out. you then do the same to the other side by taking 5 away from 13 therefor you get 8. Now you have -2x=8, take -2x and divide it into 8 and you get 4.

13 + 2x = 32x = 3 - 132x = -10x = -5

2x + y = 5 so y = 5 - 2x; This gives x - 3(5 - 2x) = 13 ie x + 6x = 13 + 15 so x = 4 and y must be -3
