Question

I think of a number, multiply it by four, and subtract three. I get eleven.

a) Using the statement above, form an equation.
Use the letter 'x' for the unknown number.
7
b) Solve the equation.

Answer 1

Answer: (x*4) - 3= 11. X = 3.5

Explanation

(4x) - 3 = 11 or (x*4) - 3 = 11.

11 + 3 = 14

So then,

14 = x * 4 (or 4x)

14 / 4 = 3.5

so,

X = 3.5
