First, distribute the 100 to the (x-1) portion:
500 = 100x - 100
then, add 100 to both sides of your equation to get “x” alone on the right side:
500 + 100 = 100x - 100 + 100
600 = 100x
next, divide 100x by 100 and 600 by 100 to isolate a singular “x”:
600/100 = 100x/100
6 = x
therefore, x=6 is your solution
Plumber a = 60x
Plumber b = 40+55x
An 8 hour job would cost the same for both plumbers. It would cost $480. Plumber a should be hired for a 5 hour job.
Because the 4 in “ 2468 “ is in the hundreds place & the 4 in “ 3548” is in the tens place.
Will start to distribute the 2 in (x-7)
so it can be (2x-2*7)=100
(2x-14)=100
2x=100+14
2x=114
x=114/2
x=57
