Question

Use substitution to solve the system of equations.

y=×+1.75
4×-2y=4
(4,4)
(3.75, 5.5)
(3.75, 0)
(5.5, 4)

Answer 1

(3.75, 5.5)

(Work is attached )
When using substitution , you substitute with a variable that is already by itself. In this case, the variable “y” is already by itself and equal to x+ 1.75 . you substitute that for the the y in the other equation and solve for the other variable which is “x”. After you solve for x , to find your y value, you have to substitute the x value in for either equation.
