Linear system word problem

Answer 1

Good job, you got the equations! XD

I'll just help you solve

Multiply the 2nd row by 9
9x+9y=117
9x+27y=207

Subtract the 2nd row from the 1st row
−18y=−90
Divide both sides by −18
y=−90/−18
Two negatives make a positive
y=90/18​​
y = 5

Substitute 5 into an equation
9x+9(5)=117
9x+45=117
Subtract 45 from both sides
9x=117−45

9x=72
Divide both sides by 9
x = ___

Hope this will help​​
