Answer: x=3, y=4
Step-by-step explanation:
We are going to use the elimination method to solve this since the x values have inverse of each other. We are going to add the 2nd equation to the 1st and we will get: y=-4 then plug y=-4 into one of the equations, then solve for x. 4(x)+5(-4)=-8, 4x-20=-8, 4x=12, x=3. So x=3, y=4
Rectangle does not have equal sides
Answer:
I will put the answer below, but here is a tip:
Use PEMDAS. PEMDAS IS THIS:
P ( ) parenthesis
E y+x exponents
M x multiplication
D ÷ division
A + addition
S - subtraction
