Answer:
You must turn the variables, or the "x" into a number to make the numbers on the left equal the numbers on the right.
Step-by-step explanation:
In order to solve these problems, you must replace the variable with a number to have the equation on the left equal what is on the right.
Equation 1:
x - 4y = -12 <----- This is the original problem.
-8 - 4y = -12 <----- Replace the variable.
-12y = -12 <----- This is a true statement.
Equation 2:
5x=20y+60 <----- This is the original problem.
5(16) =20y+60 <----- Replace the variable/Do the addition.
80 = 80y <------ This is a true statement.
Hope this helps! :D
