-4x=-40
divide -4 from both sides
x=10
Answer:
42
Step-by-step explanation:
The standard form of a line:

We have the equation of a line in the slope-point form:
use distributive property
add 3 to both sides
multiply both sides by 2
subtract x from both sides
change the signs

Subtract 6g from both sides.
-3g = -7
Divide both sites with 3.
-g = -7/3
Multiply both sides with -1
g = 7/3
