Full solution

Q. Solve using substitution.\newliney=6y = 6\newline5x−10y=−205x - 10y = -20\newline(_____, _____)
  1. Substitute yy value: Substitute the value of yy into the second equation.\newlineWe know y=6y = 6, so we can substitute this value into the second equation to find xx.\newline5x−10(6)=−205x - 10(6) = -20
  2. Simplify equation: Simplify the equation by performing the multiplication. 5x−60=−205x - 60 = -20
  3. Add 6060 to isolate: Add 6060 to both sides of the equation to isolate the term with xx.5x−60+60=−20+605x - 60 + 60 = -20 + 605x=405x = 40
  4. Divide to solve for x: Divide both sides of the equation by 55 to solve for xx.\newline5x5=405\frac{5x}{5} = \frac{40}{5}\newlinex=8x = 8
