Solve the system of equations.
y=7x
y=2x + 20

x=?
y=?

X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.

Aye bruh i don’t know this but someone else who smarter than us will answer this
