y=1/4x+7 y=-2x-2
To solve this system of equations, we can set the two equations equal to each other:
1/4x + 7 = -2x - 2
Now we can solve for x:
1/4x + 2x = -2 - 7
8x + 8 = -18
8x = -26
x = -26/8
x = -13/4
Now that we have found the value of x, we can substitute it back into one of the original equations to solve for y. Let's use the first equation:
y = 1/4(-13/4) + 7
y = -13/16 + 7
y = -13/16 + 112/16
y = 99/16
Therefore, the solution to the system of equations is x = -13/4 and y = 99/16.

Let's try to solve the system of equations again.
Given equations:
1) y = 1/4x + 7
2) y = -2x - 2
Since both equations are set equal to y, we can set them equal to each other:
1/4x + 7 = -2x - 2
Now, let's solve for x:
1/4x + 2x = -2 - 7
8/4x + 8/4 = -9/4
(8+32)/4x = -9/4
40/4x = -9/4
10x = -9/4
x = -(9/4) / 10
x = -(9/4) * (1/10)
x = -9/40
Now, substitute the value of x back into one of the equations to solve for y. We'll use the first equation:
y = 1/4(-9/40) + 7
y = -9/160 + 7
y = -9/160 + 1120/160
y = 1111/160
Therefore, the solution to the system of equations is x = -9/40 and y = 1111/160.

I apologize for the mistake. Let's correct it:
Given equations:
1) y = 1/4x + 7
2) y = -2x - 2
Since both equations are set equal to y, we can set them equal to each other:
1/4x + 7 = -2x - 2
Let's simplify this equation:
1/4x + 2x = -2 - 7
8/4x + 8 = -9
2x + 8 = -9
2x = -9 - 8
2x = -17
x = -17/2
x = -8.5
Now substitute x back into one of the original equations to solve for y. Let's use the first equation:
y = 1/4(-8.5) + 7
y = -2.125 + 7
y = 4.875
Therefore, the correct solution to the system of equations is x = -8.5 and y = 4.875.
