Solve the system of equations by substitution. Show all work neatly on your work page. Checking your answer is wise. :) Plz need this for a test 3x + 2y = 7

y = -3x +11

The table above shows approximate conversions from gallons to liters. what is the value of x?

Solve the system of equations using the substitution method. {y=−3x+7x=−2y−16 enter your answers in the boxes.
