x = 5/4; y = - 7/4
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
3x+y=2; 5x-y=8
Step: Solve3x+y=2for y:
3x+y+-3x=2+-3x (Add - 3x to both sides)
y=-3x+2
Step: Substitute-3x+2foryin5x-y=8:
5x-y=8
5x - (-3x+2) = 8
8x-2=8 (Simplify both sides of the equation)
8x-2+2=8+2 (Add 2 to both sides)
8x=10
8x
8
=
10
8
(Divide both sides by 8)
x=
5
4
Step: Substitute

forxiny=-3x+2:
y=-3x+2
y=-3 (

4
) + 2
y=

4
(Simplify both sides of the equation)
