-2 (y + 3) – 6 (y – 10) = 42
1 answer:
1 Expand.
-2y-6-6y+60=42
2 Simplify -2y-6-6y+60 to -8y+54.
-8y+54=2
3 Subtract 54 from both sides.
-8y=42−54
4 Simplify 42-54 to -12
-8y=-12
5 Divide both sides by -8.
y=-12/-8
6 Two negatives make a positive.
y=12/8
7 Simplify 12/8
y=3/2
or
y=1.5

Step-by-step explanation:
6< 3x + 9
-3x < 9-6
-3x < 3 .( -1 )
3x > 3
x > 3/3
x > 3
3x + 9 ≤ 18
3x ≤ 18-9
3x ≤ 9
x ≤ 9/3
x ≤ 3
S = {XeIR/ 3 > x ≤ 3 }
