    Problem: Solve x=8+y;−2x+6y=−20 Steps: I will try to solve your system of equations. x=y+8;−2x+6y=−20 Step: Solve x=y+8 for x: Step: Substitute (y+8) for x in −2x+6y=−20: −2x+6y=−20 −2(y+8)+6y=−20 4y−16=−20(Simplify both sides of the equation) 4y−16+16=−20+16(Add 16 to both sides) 4y=−4 4y4=−44(Divide both sides by 4) y=−1 Step: Substitute (−1) for y in x=y+8: x=y+8 x=−1+8 x=7(Simplify both sides of the equation) Answer: x=7 and y=−1
