The solution of 2x + 5 equals 40
2x+5=40
Subtract 5 from both sides of the equation
2x=40-5
2x=35
Divide both sides of the equation by two
x=17.5
15 / 7 times () + 7 / 2 times 15 / 8 equals 7 / 2

X minus y equals 0. What's the ratio between X and y?
Because: X-Y = 0
x=y
X = 1
So: X is proportional to y
