Answer:
x = -6
Step-by-step explanation:
-5(x + 3) = 15
Distribute the -5
-5x -15 =15
Add 15 to each side
-5x-15+15 =15+15
-5x = 30
Divide each side by -5
-5x/-5 = 30/-5
x =-6
Answer:
y = 5
Step-by-step explanation:
If the line is parallel to the x-axis, regardless of the value of x, the value of y must remain at y = 5. Therefore, x can be any number, (x,5), including -2.

Step-by-step explanation:
Answer:
v = 66/7
Step-by-step explanation:
Step 1: Write equation
-7v + 3 = -63
Step 2: Solve for <em>v</em>
<u>Subtract 3 on both sides:</u> -7v = -66
<u>Divide both sides by -7:</u> v = 66/7
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-7(66/7) + 3 = -63
-66 + 3 = -63
-63 = -63
