ANSWER: x = 5.5
EXPLANATION:
To find x, set the equation equal to 0.
4(3 - x) + 10 = 0
Use PEMDAS. parenthasis first!
Distribute the 4 into the 3 - x (multiply 4 by each)
12 - 4x + 10 = 0
Combine like terms. (12 and 10)
12 + 10 = 22
22 - 4x = 0
Isolate x by subtracting 22 from the side with x.
-4x = -22
Isolate x by dividing 4.
22 divided by 4 = 5.5
-x = -5.5.
Now divide by -1 to make x positive.
x = 5.5
