Answer:
87
Step-by-step explanation:
15+(+72)--> 15+72
15+72=87
Since this is a system of equations, substitute the value of x into the other equation.
2(3y)+2y=24
6y+2y=24
8y=24
y=3
x=3(3)
x=9
To check my work, substitute my x and y values:
2(9)+2(3)=24
18+6=24
24=24
Your answer is (3,9)
Hope this helps! Have a wonderful day :)
