Simplify 3.8x + 5.2x - 6.7 to 9x - 6.7
9x - 6.7 = 11.3
Add 6.7 to both sides
9x = 11.3 + 6.7
Simplify 11.3 + 6.7 to 18
9x = 18
Divide both sides by 9
x = 18/9
Simplify 18/9 to 2
x = 2
Answer:
x=2
Step-by-step explanation:
3.8x + 5.2x - 6.7 = 11.3
Combine like terms
Add 6.7 to each side
9x - 6.7+6.7 = 11.3+6.7
Divide each side by 9
9x/9 = 18/9
x =2
