Answer: The value of y is -10 when x=26.
Explanation:
The given equation is,
[tex]-x-3y=4[/tex]
Put x = 26 in the above equation,
[tex]-26-3y=4[/tex]
Add 26 both sides in the above equation.
[tex]-3y=4+26[/tex]
[tex]-3y=30[/tex]
Divide both sides by 3.
[tex]\frac{-30}{3} =\frac{3y}{3}[/tex]
[tex]-10=y[/tex]
Therefore, when x=26 the value of y is -10.
