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.
it is -7 because the 2 make it like that
i dont know the rest but the answer to x is 15 because the formula to that triangle is A^2+B^2=C^2
A=12
B=9
144(12^2) and 81 (9^2) add
225
find square root
15
z=15
