Answer x=22/5 or 4.4
Step-by-step explanation:
1. Combine like terms
15x-12=54
2. Add 12 to both sides
15x=66
3. Divide both sides by 15
15x/15=66/15
4. x=22/5 or 4.4

Answer:
x = 4.4
Step-by-step explanation:
This equation has x-terms on one side of the equal sign and constants on both sides.
First, collect terms.
15x -12 = 54
Then add the opposite of the constant that is on the same side as the x-term.
15x = 66
Now, divide by the coefficient of x.
x = 66/15 = 22/5
x = 4.4
