Answer:
hope this helps, your answer should be (-5,8)
x = -5, y = 8
Explanation:
we're gonna start by subtracting
3x + 2y = 1 x+y=3
Rewrite the equation:
x + y = 3 , 3 x + 2 = 1
Step: Solve x + y = 3 for x:
x + y = 3
x + y + −y = 3 + −y (Add -y to both sides)
x = −y + 3
Step: Substitute −y + 3 for x in 3x + 2y = 1:
3x + 2y = 1
3 (−y + 3) + 2y = 1
−y + 9 = 1 (Simplify both sides of the equation)
−y + 9 + −9 = 1 + −9 (Add -9 to both sides)
−y = −8
−y/−1 = −8/−1 (Divide both sides by -1)
y=8
Step: Substitute 8 for y in x=−y+3:
x = −y + 3
x = −8 + 3
x = −5 (Simplify both sides of the equation)
