Solve using elimination
y = 3x + 4
y = 2x + 2
1 answer:
Answer:
x=-2
y=-2
Step-by-step explanation:
express the system in standard form
-(3x)+y=4 (equation 1)
-(2x+4y=2 (equation 2)
------------------
Subtract 2/3x(equation 1) from equation 2
-(3x)+y=4 (equation 1)
0x+y/3=-2/3 (equation 2)
-----------------
Multiply equation 2 by 3
-(3x)+y=4 (equation 1)
0x+y=-2 (equation 2)
----------------
Subtract equation 2 from equation 1
-(3x)+0y=6 (equation 1)
0x+y=-2 (equation 2)
----------------
Divide equation 1 by -3:
X+0y=-2 (equation 1)
0x+y=-2 (equation 2)
