Full solution

Q. −4x+7=15 -4 x+7=15
  1. Subtract 77 to isolate x: Subtract 77 from both sides of the equation to isolate the term containing x.\newline−4x+7−7=15−7-4x + 7 - 7 = 15 - 7\newline−4x=8-4x = 8
  2. Divide by −4-4 to solve: Divide both sides of the equation by −4-4 to solve for xx.−4x/−4=8/−4-4x / -4 = 8 / -4x=−2x = -2
