1.
for |a|=b assume a=b and a=-b
|2-3x|=7 solve
2-3x=7 and 2-3x=-7
minus 2 both sides
-3x=5 and -3x=-9
divide both sides by -3
x=-5/3 and x=3
D
2. minus 4x both sides and divide by 3
y=-4/3x-4
B
3.
divide both sides by 2 and add w to both sides
A/2+w=m
D
1.D
2.B
3.D
distribute, add 2w to both sides and divide by 2
