Question

Form the expression of following statement:- a) x multiplied by 5 b) x added to -5

Answer 1

Answer: Answer

(i) 5x+3y

(ii) 72y−32x

Solution

5 times of x is 5x.

3 times x is 3y

If 5 times of x is added to 3 times of y, then the expression is 5x+3y,

(ii) One nad half time x=12x=32x

Three and half times of y=312y=72y

One of half times of x subtracted from three and half of y is 72y=32x.

Answer 2

$a) \: \: x \times 5 = 5x$

$b) \: \: x + ( - 5) = x - 5$
