x 5 154 = 6 \frac{x}{5}-154=6

x 5 = 160 \frac{x}{5}=160

x = 800 x=800

same solution.

Go reverse 154+6=160

160*5=800

Quotient=154+6=160 Number=160*5=800 Check: 160-154=6 800/5=160

quotient-154=6 therfore quotieent=160 So the number is 160*5=800

this is basic maths,nothing else.

Suppose that the number is x meaning that x 5 154 = 6 \frac{x}{5} - 154= 6 .That means that x 5 = 160 \frac{x}{5} =160 then meaning that x = 160 5 = 800 x=160*5=800

Let the required number be x

Then,

(x / 5) - 154 = 6

Or, x / 5 = 154 + 6

Or, x / 5 = 160

Or, x = 160 * 5

Hence, x = 800

800

Just right the equation and solve it

Let the required number be x

Then,

(x / 5) - 154 = 6

Or, x / 5 = 154 + 6

Or, x / 5 = 160

Or, x = 160 * 5

Hence, x = 800
