A repairman charges $50.25 per visit plus $35.50 per hour. For how many hours did the repairman work if the total bill was $210.00? HELP ME MATE RIGHT NOW I AM HAVING A TEST.

5.8 hours

Step-by-step explanation:

50.25x + 35.50y = 210.00

50.25x = -35.50y + 210.00

x = (-35.50y+210.00)/50.25

50.25((-35.50y+210)/50.25) + 35.50y = 210

-1783.875y + 10552.5 = 210

-1783.875y = -10342.5

y = 5.797771705

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

what is the question?
