Answer:
79/9 or 8 7/9
Step-by-step explanation:
1+9x=80
1 +9x = 90
Subtract 1 from each side
1+9x-1 = 80-1
9x = 79
divide by 9
9x/9 = 79/9
x = 8 7/9
Answer:
The answer is x= 9.9
Step-by-step explanation:
3= x/3.3
Switch sides:
x/3.3 = 3
Multiply both sides by 3.3:
3.3x/3.3 = 3* 3.3
Simplify:
x= 9.9
Hope this helped :)
