Question

y = x + 4
y = −2x − 2 

Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.

mathmate · Answer

You can use the method of comparison.
Since both equations show the value of y on the right-hand side, and since y=y, so we can write x+4=-2x-2 and hence solve for x (one equation, one unknown).
Once x is found you can substitute its value into one of the two equations to find y.
