The answer: x=857 and y=-401
Set up the two equations
X+2y=55
2x+y=1313
Solve the system of equations by elimination
2x+y=1313
-2x-4y=-110
Add each of the corresponding terms together
-3y=1203
Divide by -3
Y=-401
Plug y back into one of the original equations
X+2(-401)=55
X-802=55
X=857
Step-by-step explanation:
y=12when x=5
y=5+7
when x=3
y=3+7=10
The identity property of addition is any number plus zero equals that number.
the commutative property of addition is when the order of the numbers does not change the sum.
