Answer:
x = 4.5
Step-by-step explanation:
there's definitely other ways to solve this, but I used a proportion.
Then you can make this equation:
14x = 3.5 * 18
I solved for it and got 4.5 .
Technically this is a line segment, but since that is not an option. choose the answer “line”

Answer:
y = -4
Step-by-step explanation:
3y - 2(5y - 7) = -9y + 6 (Given)
3y - 10y + 14 = -9y + 6 (Distribute)
-7y + 14 = -9y + 6 (Add like terms)
2y + 14 = 6 (Add 9y on both sides)
2y = -8 (Subtract 14 on both sides)
y = -4 (Divide 2 on both sides)
You can check by substituting the solution for y:
3(-4) - 2(5(-4) - 7) = -9(-4) + 6
-12 - 2(-20 - 7) = 36 + 6
-12 - 2(-27) = 42
-12 + 54 = 42
42 = 42
