Answer:
y=4
x= 3/7
Step-by-step explanation:
2y=8
Divide both sides by 2
2y÷2=8÷2
A.) y=4
Substitute 4 for y
7x−2y=−5
7x+(−2)(4)=−5
Simplify both sides of the equation.
7x−8=−5
Add 8 to both sides
7x−8+8=−5+8
7x=3
Divide both sides by 7
7x÷7= 3÷7
x= <u>3</u>
7
Its is 74 because you add all of them then subtract it from the total which in your case is 360
Answer:
6x + 200 = 17,000
Step-by-step explanation:
Lower level = 4x - 300
Mid level = 2x + 500
Combine the two equations to find the number of seats in the upper level
(2x + 500) × (4x - 300) = 17,000
Combine like terms
4x × 2x + 500 - 300 = 17,000
<em>6x + 200 = 17,000</em>
