Question

Solve the system of equations. show your work/explain how you found your answer.

2x-4y=10
x+5=40

Answer 1

Look at step-by-step explanation

Explanation:

Work on the second equation first.

x + 5 = 40

Get all variables on one side:

x = 35

You now have the answer for the variable of x, use this on the first equation:

2x-4y=10

2(35)-4y=10

Subtract 70 from both sides:

70-4y=10

Divide both sides by neagtive 4:

-4y=-60

y=15
