Answer:
3
Step-by-step explanation:
The whole goal is to isolate the variable.
3x-1=8
1+3x-1=8+1 first add 1 to both sides of the equation to cancel out the -1
3x=9 now just divide 3 to both sides of the equation because the opposite of multiplication is division. So dividing 3 on both sides cancels out the 3 to isolate the x
3x/3=9/3
x=3
Answer:
The answer is 153.8
Step-by-step explanation:
