Answer:
x=2 and y=−1
Rewrite equations:
x+y=1;3x−2y=8
Step: Solve x+y= 1for x:
x+y=1
x+y+−y=1+−y( add y to both parts of equation
x=−y+1
Step: Substitute−y+1forxin3x−2y=8:
3x−2y=8
3(−y+1) −2y=8
−5y+3=8(Simplify both sides of the equation)
−5y+3+−3=8+−3(Add -3 to both sides)
−5y=5
−5y
−5
=
5
−5
(Divide both sides by -5)
y=−1
Step: Substitute−1foryinx=−y+1:
x=−y+1
x=−(−1)+1
x=2(Simplify both sides of the equation)
Step-by-step explanation:
