1)
2x + 1 = 6x -11
6x-2x = 1 + 11
4x = 12
x = 3
y = 2x + 1
y = 2(3) + 1
y = 7
2)
3x + 5 = 5x - 5
3x - 5x = -5-5
-2x = -10
x = 5
y = 3x +5
y = 3(5) + 5
y = 20
3)
4x - 2 = x + 10
3x = 12
x = 4
y = 4x - 2
y = 4(4)-2
y = 14
4)
7x - 5 = 3x + 3
7x - 3x = 3 + 5
4x = 8
x = 2
y = 3x + 3
y = 3(2)+3
y = 9
5)
-2x + 4 = -3x + 5
-2x + 3x = 5 - 4
x = 1
y = -2x + 4
y = -2(1) +4
y = 2
6)
-5x - 3 = 4x + 15
-5x - 4x = 15 + 3
-9x = 18
x = -2
y = 4x + 15
y = 4(-2) + 15
y = 7
7)
-x + 7 =2x-11
-3x = -18
x = 6
y = -x + 7
y = -6 + 7
y = 1
8)
6x - 2 = -2x + 14
8x = 16
x = 2
y = 6x -2
y = 6(2) - 2
y = 10
