Answer:
(2,-1)
Step-by-step explanation:
Given system of equations:
We are going to use the substitution method.
Step 1: Solve for x = y + 3 for x:
(Substitute y + 3 for x in 3x + 2y = 4)
3x+2y=4
3(y+3)+2y=4
5y + 9 = 4 ----> Simplify both sides of the equation
5y+9+−9=4+−9 -------> Add -9 to both sides
5y=−5
5y5 = -5/5 ------> Divide both sides by 5
y = −1
Step 1: Substitute -1 for y in x = y + 3:
x = y + 3
x = -1 + 3
x = 2 --------> (Simplify both sides of the equation)
Answer:
(2,-1)
