Kitty [74]

Answer:

e = 10

Step-by-step explanation:

9e+4=-5e+14+13e

Combine like terms

9e+4=14+8e

Subtract 8e from both sides

9e-8e+4=8e-8e +14

e +4 = 14

Subtract 4 from each side

e+4-4 = 14-4

e = 10

Let h equal the number of hours the electrician works.

We can write the equation like this:

90h + 60 = 600

Solve for h.

90h + 60 = 600

~Subtract 60 to both sides

90h + 60 - 60 = 600 - 60

~Simplify

90h = 540

~Divide 90 to both sides

90h/90 = 540/90

~Simplify

h = 6

Therefore, the electrician work for 6 hours.

The correct answer is Option 1.

Best of Luck!
