Answer:

No Solutions

Step-by-step explanation:

1. Substitute the 2x + 1 in for the y in the first equation. Rewrite it as 2x - (2x + 1) = 2.

2. Add the opposite and change the equation to 2x + -1(2x + 1) = 2.

3. Use the distributive to make the equation look like this: 2x + -2x + -1 = 2

4. Combine like terms and add 2x and -2x. They cancel each other out.

5. You will end up with -1 ≠ 2. Since -1 and 2 are not equal, there are no solutions.

Y=2x+1
2x-y=2
2x-(2x+1)=2
-1=2
-1+1=2+1

What is the answer for 2(3a-12)=3(2a-8)​
Setler [38]

Answer:

6a-24=6a-24

Step-by-step explanation:

you distribute the 2 on the first equation (2(3a-12)) so 2 times 3a is 6a and -12 times 2 equals -24 so the simple form for the first equation is 6a-24. You do the same for the second equation 3 times 2a is 6a and 3 times -8 is -24. So the equations are the same on each side meaning they have infinite solutions on a graph.
