a) 2x-6x+2x=12+6x-8x
= -2x = 12 - 2 x
= - 2 x + 2 x = 12
= 0
b) 3x-12+3x=12x-16+2
= 6x - 12 = 12x -14
= -12 = 6x - 14
= - 12 + 14 = 6x
= 2 = 6x
= 2/6 = x
c) 5y-10+7y+2=5y+16
= 12 y - 8 = 5y + 16
= 7 y = 24
y = 24/7
d) 15y-7y+2y+2=7y-y+6
= 10 y + 2 = 6y + 6
= 4y = 4
y = 1
= -2x = 12 - 2 x
= - 2 x + 2 x = 12
= 0
b) 3x-12+3x=12x-16+2
= 6x - 12 = 12x -14
= -12 = 6x - 14
= - 12 + 14 = 6x
= 2 = 6x
= 2/6 = x
c) 5y-10+7y+2=5y+16
= 12 y - 8 = 5y + 16
= 7 y = 24
y = 24/7
d) 15y-7y+2y+2=7y-y+6
= 10 y + 2 = 6y + 6
= 4y = 4
y = 1

A) 2x-6x+2x-6x+8x= 12
-4x=12
x= -3
B) 3x-12+3x = 12x - 16 + 2
3x + 3x - 12x = -16 + 2 + 12
-6x = -2
x= 1/3
C) 5y-10+7y+2=5y+16
5y + 7y - 5y = 16 + 10 -2
7y= 24
y= 24/7
D) 15y-7y+2y+2=7y-y+6
15y - 7y + 2y - 7y + y = 6 - 2
4y = 4
y = 1
E) 2z-z+13z-6+z+4z= 0
19z = 6
z = 6/19
-4x=12
x= -3
B) 3x-12+3x = 12x - 16 + 2
3x + 3x - 12x = -16 + 2 + 12
-6x = -2
x= 1/3
C) 5y-10+7y+2=5y+16
5y + 7y - 5y = 16 + 10 -2
7y= 24
y= 24/7
D) 15y-7y+2y+2=7y-y+6
15y - 7y + 2y - 7y + y = 6 - 2
4y = 4
y = 1
E) 2z-z+13z-6+z+4z= 0
19z = 6
z = 6/19
