    I will try to solve your system of equations. x=y+5;28x−9y=−12 Step: Solve x=y+5 for x: Step: Substitute (y+5) for x in 28x−9y=−12: 28x−9y=−12 28(y+5)−9y=−12 19y+140=−12(Simplify both sides of the equation) 19y+140+−140=−12+−140(Add -140 to both sides) 19y=−152 19y19=−15219(Divide both sides by 19) y=−8 Step: Substitute (−8) for y in x=y+5: x=y+5 x=−8+5 x=−3(Simplify both sides of the equation) Answer: x=−3 and y=−8
