Answer:
x = 2
Step-by-step explanation:
3x + 4 - x = 8
Combine like terms
2x + 4 = 8
-4 from both sides
2x = 4
Divide by 2
x = 2
Answer:
x=4
Step-by-step explanation:
Add 4 to both sides of the equation
3x=8+4
add 8 and 4
3x=12
Divide each term in 3 x = 12 by 3.
3x/3 = 12/3
Cancel the common factor.
3x/3 = 12/3
Divide x by 1.
x = 12/3
Divide 12 by 3.
