Steps:I will try to solve your system of equations.
y=−8x+23;−7x+2y=−23
Step: Solve y=−8x+23 for y: Step:
Substitute−8x+23 for y in −7x+2y=−23:
−7x+2y=−23−7x+2(−8x+23)=−23−23x+46=−23(Simplify both sides of the equation)−23x+46+−46=−23+−46(Add -46 to both sides)−23x=−69−23x−23=−69−23(Divide both sides by -23)x=3Step: Substitute 3 for x in y=−8x+23:y=−8x+23y=(−8)(3)+23y=−1(Simplify both sides of the equation)
Answer:y=−1 and x=3
