Answer:
Step-by-step explanation:
x−y=2;3x+2y=16
Step: Solvex−y=2for x:
x−y+y=2+y(Add y to both sides)
x=y+2
Step: Substitutey+2forxin3x+2y=16:
3x+2y=16
3(y+2)+2y=16
5y+6=16(Simplify both sides of the equation)
5y+6+−6=16+−6(Add -6 to both sides)
5y=10
5y
5
=
10
5
(Divide both sides by 5)
y=2
Step: Substitute2foryinx=y+2:
x=y+2
x=2+2
x=4(Simplify both sides of the equation)
