Answer:
Step-by-step explanation:
y = 3x + 2
6x – 2y = 10
Ryan’s answer:
I solved by adding the equations. The solution is .
y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =
6x – 2y = 10 → 6 – 2y = 10
7 – 2y = 10
–2y = –3
y = -
Jesse’s answer:
I used matrices. The solution is .
Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.
(a)36 = 6
(b)81 = 9
(c)256 = 16
(d)196 = 14
Answer:
x=0
Step-by-step explanation:
combine like terms on both sides of the equal sign
-9+x= x-7
move similar terms to the same side
-2=0x
divide both sides by x
x=0
