2x + 5 = 13 2x = 8 x = 4

2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4

2x-3y=13

2x + 1 = 13; 2x = 12; x = 6

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

X=44.5

2x plus 3y

x=(-9)

it equals 13X.

-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

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

x over 4= 2x+3 over 15

2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans

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

-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4

x=1

x = 3 and y = 2

6x+13=-2x-19 so 8x=-19-13=-32 so x=-4

What number when doubled has seven added and gives 13?
