To solve the system of equations:
4x - y = -3 ----(1)
6x - y = -8 ----(2)
You can solve this system using different methods such as substitution, elimination, or matrix method.
Using the substitution method:
From equation (1), rearrange it to solve for y:
y = 4x + 3
Substitute this value for y in equation (2):
6x - (4x + 3) = -8
6x - 4x - 3 = -8
2x - 3 = -8
Add 3 to both sides:
2x = -5
Divide by 2:
x = -5/2 = -2.5
Now substitute the value of x back into equation (1) to find y:
4(-2.5) - y = -3
-10 - y = -3
Add 10 to both sides:
-y = 7
Multiply by -1:
y = -7
Therefore, the solution to the system of equations is x = -2.5, y = -7.
