Answer:
x = 1
Step-by-step explanation:
9 + 3x = 18 - 6x
3x + 6x = 18 - 9
9x = 9
X = 1
Answer:
Step-by-step explanation:
9+3x =6(3-x)
9+3x =6 ×3 - 6x
9+3x =18 -6x
Collect like terms
9-18= -6x-3x
-9 =-9x
Divide both sides by -9
-9/-9 =-9x/-9
Minus cancels minus and 9 divided by 9 is 1 on both sides
1 =x
x =1
