Answer:
x = 5, y = 10
Step-by-step explanation:
I will find y first then use the value of y to find x.
2x+4y+6 = 56
2x+4y = 56-6
2x+4y = 50
I will simplify the equation by dividing both sides by 2.
x + 2y = 25
Isolate x.
x = 25-2y
Then, I will substitute x = 25-2y into the equation 2y-4 = x+11
2y-4 = x+11
2y-4 = 25-2y+11
Simplify.
2y-4 = 36-2y
Put the like terms together.
2y+2y = 36+4
Evaluate.
4y = 40
Find y.
y = 40 ÷ 4
y = 10
Now that we have found y = 10, we can substitute that into x = 25-2y
x = 25-2y
x = 25-2(10)
Evaluate.
x = 25-20
Find x.
x = 5
