Answer:
x= -1 and y= -1
Step-by-step explanation:
Power through with me as I explain this, its a bit long of an explanation.
To solve the following system of equations, we need to write 5x-4y=-1 in slope-intercept form.
Subtract 5x from both sides.
Divide each term by -4.
Remember that dividing two negative values results in a positive value.
Reorder the terms. (Reordering terms makes the work tidier, it does not change the result)
Now that we have the slope-intercept form, we can solve by subsitution with the two equations to find the solution.
Substitute for <em>y </em> in .
Subtract 1/4 from each side.
Simplify the left side.
Simplify the right side.
Subtract 6x from both sides.
Simplify.
Simplify the left side of the equation by factoring out <em>x.</em>

Multiply each side by 4.
Divide both side by 19.
Now that we know the value of x, we need to find y.
Insert the value of x in the equation y= 6x+5
Thus, x= -1 and y= -1 OR (-1,-1)
