Answer:
x = 1 and x = 3
Step-by-step explanation:
Let's solve your system by substitution.
y=2x+1;y=3x
Step: Solvey=2x+1for y:
y=2x+1
Step: Substitute2x+1foryiny=3x:
y=3x
2x+1=3x
2x+1+−3x=3x+−3x(Add -3x to both sides)
−x+1=0
−x+1+−1=0+−1(Add -1 to both sides)
−x=−1
−x
−1
=
−1
−1
(Divide both sides by -1)
x=1
Step: Substitute1forxiny=2x+1:
y=2x+1
y=(2)(1)+1
y=3(Simplify both sides of the equation)
Answer:
x=1 and y=3
