Will fan and medal!!
Consider the following pair of equations:
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.
I know the steps of the process but I dont know how to find the value of x...

Best ResponseYou've already chosen the best response.1you know that: 1) y is equal to x+4 from the first equation 2) y is equal to 2x2x from the second equation if y is equal to x+4 and 2x2, then x+4 is equal to 2x2. (agree?)
