distributive property
Answer:
x= -4,-14
Step-by-step explanation:
Try first to solve the equation by factoring. Be sure that your equation is in standard form before you start your factoring attempt.
12 - x = 5
Subtract 12 from both sides
12 - 12 - x = 5 - 12
- x = - 7
Divide both sides by -1
-x/-1 = -12/-1
x = 7
Answer:
149
Step-by-step explanation:
easy
(3x+3) + (4x + 2)
------------------------- = 13
2
13(2) = (3x+3) + (4x+2)
26 = 3x + 3 + 4x + 2
26 = 7x + 5
26-5 = 7x
21 = 7x
x = 21 ÷ 7
x = 3
