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
