Answer the question.5x + 3y = 197x + 8y = 48If your friend was going to solve this system of equations by first eliminating y, what general suggestions would you make so your friend could start on this in a systematic way?

What will be an ideal response?


Answers may vary. One possibility: Multiply the first equation by -8, multiply the second equation by 3, and add the two resulting equations together. Solve the resulting equation for x. Substitute the solution for x into one of the original equations and solve for y. Finally, check your overall solution by substituting both values into the other original equation.
