Answer
[tex]x=\frac{11}{3}[/tex]
Explanation
Based on the given conditions, formulate:: [tex]y=3[/tex]
Substitute [tex]y=3[/tex] into [tex]y=-6x+25[/tex] :: [tex]3=-6x+25[/tex]
Rearrange variables to the left side of the equation: [tex]6x=25-3[/tex]
Calculate the sum or difference: [tex]6x=22[/tex]
Divide both sides of the equation by the coefficient of variable: [tex]x=\frac{22}{6}[/tex]
Cross out the common factor: [tex]x=\frac{11}{3}[/tex]
