Translate: One number "x" is "=" three times "3*" another number "y"
Their sum "x+y" is "=" 180
x = 3y
x + y = 180
Substitute the first equation into the second, since x=3y, just plug it in
(3y) + y = 180
clean up
4y = 180
divide by 4
y = 45
Now, since x=3y and y=45, x must be 135
does it check?
135 = 3 * 45 ◄
135 + 45 = 180 ◄
Yes, so the answer is correct.
