Answer:
x=4 and y=1
Explanation:
Let's solve your system by substitution.
2x+3y=11;y=x−3
Rewrite equations:
y=x−3;2x+3y=11
Step: Solve y=x−3 for y:
y=x−3
Step: Substitute x−3 for y in 2x+3y=11:
2x+3y=11
2x+3(x−3)=11
5x−9=11 (Simplify both sides of the equation)
5x−9+9=11+9( Add 9 to both sides)
5x=20
5x/5=20/5
(Divide both sides by 5)
x=4
Step: Substitute 4 for x in y=x−3:
y=x−3
y=4−3
y=1(Simplify both sides of the equation)
Answer:
x=4 and y=1
