Answer: Undefined
Step-by-step explanation:
4y+x=12, 2x=24-8y
Isolate x by subtracting 4y
4y+x=12
x=12-4y
Plug the equation for x in to anywhere you see the variable x in the other equation
2(12-4y)=24-8y
Distribute 2
24-8y=24-8y
Get the variables on one side so add 8y (cancels out)
24=24
Can’t solve its undefined
In order to subtract fractions, you need the denominators (bottom number) to be the same.
.
4. 3(3) + 2
(3 x 3) + 2 = 11
5. -(-6) -7
(+)6 -7 = -1
