Answer:
x=3
Step-by-step explanation:
There's many ways you can begin this, I prefer getting rid of the fraction first.
Multiply both sides by 3/2 (yes, I switched it on purpose)
You get. . .
5x-6 = 9
To isolate the 5x, add 6 to both sides
5x = 15
Divide both sides by 5 and you get . . .
x=3
The number of years is 3 because 6612 divided by 58 is 114 and 114-111=3...
Quotient=Division.33075/35=945
945 is your answer.
Since both equations are equal to y you can just make them equal to each other, like this 3x + 7 = x - 9. From there isolate the varible x on one side so that the solution will be on the other side of the equation. I'll do the steps too for you.
3x + 7 = x - 9
2x + 7 = -9
2x = -16
x = -8
Hope this helps :)
