Answer:
x=1 and y=7
Step-by-step explanation:
7x−2y=−7;y=7
Rewrite equations:
y=7;7x−2y=−7
Step: Solve y = 7 for y:
y=7
Steps: Substitute 7 for y in 7x−2y=−7:
7x−2y=−7
7x+(−2)(7)=−7
7x−14=−7 (Simplify both sides of the equation)
7x−14+14=−7+14 (Add 14 to both sides)
7x=7
7x/7 = 7/7 (Divide both sides by 7)
x = 1
So the answer is, x=1 and y=7
Answer:x + 5y is greater than or equal too $50
Step-by-step explanation:
If x is equal to the amount of $1 then there is no need for a coefficient. Being that y is represented as $5 there needs to be a coefficient of because it’s five dollars times however many you have. Then it is greater than or equal to $50 because the problem states there is at least $50 in the register.
