Q. Solve.\newline−10x−7y=−9-10x - 7y = -9\newlinex+3y=17x + 3y = 17\newline(_____, _____)
  1. Solve for x: Step 11: Solve the second equation for x.\newlinex+3y=17x + 3y = 17\newlinex=17−3yx = 17 - 3y
  2. Substitute xx: Step 22: Substitute xx in the first equation.\newline−10(17−3y)−7y=−9-10(17 - 3y) - 7y = -9\newline−170+30y−7y=−9-170 + 30y - 7y = -9\newline23y−170=−923y - 170 = -9
  3. Solve for y: Step 33: Solve for y.\newline23y=16123y = 161\newliney=7y = 7
  4. Substitute yy into xx: Step 44: Substitute yy back into the equation for xx.x=17−3(7)x = 17 - 3(7)x=17−21x = 17 - 21x=−4x = -4
