Answer:
the first one
the third one
the fourth one
Step-by-step explanation:
1. x <em>does</em> equal 9
2. the equation would lead to x being canceled out so there would be an x in your answer
3. x <em>does</em> equal 30
4. x <em>does</em> equal 6
5. x should equal 135
-47 = x + 15
Rearrange it to isolate x:
-47 - 15 = x
-62 = x
Since y is anything greater than 2, you would draw a straight line across the point (from left to right) and if you had to shade you would shade above it (:
You could do 33, 36, 39, 42
