Answer:
x=8 and y=23
Step-by-step explanation:
Rewrite equations:
y=2x+7;y=3x−1
Step: Solve y=2x+7 for y:
y=2x+7
Step: Substitute 2x+7 for y in y=3x−1:
y=3x−1
2x+7=3x−1
2x+7+−3x=3x−1+−3x(Add -3x to both sides)
−x+7=−1
−x+7+−7=−1+−7(Add -7 to both sides)
−x=−8−x−1=−8−1
(Divide both sides by -1)
x=8
Step: Substitute 8 for x in y=2x+7:
y=2x+7
y=(2)(8)+7
y=23(Simplify both sides of the equation)
