SOLUTION:

Case: Systems of equations

Given:

X=17-4y

Y=x-2

Method:

Solving substitution.

We replace the expression of y in the first equation.

X=17-4y

x=17-4(x-2)

x = 17 -4x +8

x + 4x = 17 + 8

5x = 25

x= 25/5

x= 5

Finding y

Plug the value of x ino equation 2

Y=x-2

y= 5 - 2

y= 3.

Solution set (5, 3)

Final answer:

(5, 3)
