# I'm thinking of a number.

I'm thinking of a number. I multiply it by 14 and add 11. I get the same answer is I multiply by 4 and add 131. Whats my number? (MyMaths Solving Equations Online Homework, Q2.)

let's call the number Y. So, 14Y + 11 is the same answer as 4 Y +131. Or put another way, 14 Y + 11 = 4 Y + 131.

this means 14 Y - 4 Y = 120 or 10 Y = 120

So, 14Y = 4 Y + 131 - 11 = 4 Y + 120

if 10 Y = 120. Y = 12 and the number you are thinking of is 12
