Q. Solve using elimination.\newline−9x+10y=−10−2x+y=10 \begin{array}{l} -9 x+10 y=-10 \\ -2 x+y=10 \end{array} \newline□ \square \newline□ \square \newlineSubmit
  1. Multiply by 1010: Multiply the second equation by 1010 to make the yy coefficients match.−2x+y=10-2x + y = 10 becomes −20x+10y=100-20x + 10y = 100
  2. Add equations: Add the new equation to the first one.\newline(−9x+10y)+(−20x+10y)=−10+100(-9x + 10y) + (-20x + 10y) = -10 + 100
  3. Combine like terms: Combine like terms.\newline−9x−20x+10y+10y=−10+100-9x - 20x + 10y + 10y = -10 + 100
  4. Simplify equation: Simplify the equation. −29x+20y=90-29x + 20y = 90
