Q. Solve using substitution.y=65x−10y=−20(_____, _____)
Substitute y value: Substitute the value of y into the second equation.We know y=6, so we can substitute this value into the second equation to find x.5x−10(6)=−20
Simplify equation: Simplify the equation by performing the multiplication. 5x−60=−20
Add 60 to isolate: Add 60 to both sides of the equation to isolate the term with x.5x−60+60=−20+605x=40
Divide to solve for x: Divide both sides of the equation by 5 to solve for x.55x=540x=8
