When we substitute a specific valuefor each variable, and then perform the operations, it's called evaluating theexpression. Let's evaluate theexpression 3y + 2y when 5 = y. Click on the steps to see how it's done. Perform the operations, to find the value of the expression.
Answer:
4x - y = -3y = 5x
Write as a system
4x-y = 5x
-3y = 5x
Simplify the expressions
-x-y = 0
-5x-3y = 0
Multiply both sided by -5
5x + 5y = 0
-5x - 3y = 0
2y = 0
y = 0
Substitute the value of y into the equation
-x-0= 0
x=0
A possible solution is (x,y) = (0,0)
