Translate to a system of equations and solve using the addition method.

The sum of two numbers is88. The difference is 22.Find the numbers?

My answer:

I started but i think that i am wrong.

x + y = 88

y = -x +88

y = -1x + 88

now once i substituted

x -1x + 88 = 88

see i don't know if i am doing this correctly.

You wrote only one equation and you need two.

x+y=88 is ok

The second equation is

x-y=22.Also note that the problem asks for a solution by addition, not by substitution.

solve for x and y.

so then that means that the solution is (55,33)

yes
