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
xy=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
