8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4

For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x

x=4

If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0

0 because X= -1

3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.

3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3

8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4

For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x

3x+2 = 5x so 2x = 2 and hence x = 2/2 = 1

2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1

5x-3x+x+8 = 2x+1+x+x 3x+8 = 4x+1 3x-4x = 1-8 -x = -7 x=7 Hope that helps.

6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
