Answer:
4
Step-by-step explanation:
The y-coordinate of the point where both lines intersect will give us the same solution for x.
At y = 4, both equations will have a corresponding x-value of 1.
Therefore, the value of y that that will make both equations have the same solution of x is 4.

Answer:
The answer to your question is: 12
Step-by-step explanation:
You have a function with two conditions,
- the first condition do not consider number nine, because it uses the symbol <, then we can not evaluate nine in this function.
- the second condition considers nine because uses the symbol ≤ which means that nine is considered here, but the function equals 12, so that is the solution.
Answer:
Step-by-step explanation:
Hello,
Pls post the full question next time so that we can make sure what is expected.
I assume that you want to solve for (x,y)
(1) 2x + 3y = 7
(2) 3x + 2y = 8
2*(2)-3*(1) gives
2*3x + 2*2y - 3*2x - 3*3y = 2*8 - 3*7 = 16 - 21 = -5
6x - 6x + 4y -9y = -5
-5y=-5
y = 1
and we can replace in (1)
2x + 3*1 = 7
2x = 7 - 3 = 4
x = 2
hope this helps
