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)
