A) -2x+2=-8
-2 -2
-2x = -10
/-2 /-2
x = 5
C)3y-9+y=6
4y-9= 6
+9 +9
4y = 15
/4 /4
y = 3.75
D) 9-(2+(-3y)) = 6+2y-(5+y)
9-(2-3y) = 6+2y-(5+y)
9-(2-3y) : 3y+7
6+2y-(5+y) : y+1
3y+7 = y+1
-7 -7
3y = y-6
-y -y
2y = -6
/2 /2
y = -3
There is no real solution for B However we can set it to 0
B) 4x+x-2 = 2x+8+3x
group like terms and add similar elements
5x-2 = 5x+8
+2 +2
5x = 5x + 10
/5x / 5x
0 = 10
