Question

Simplify
3x+x​/y−y²
when x=6 and y= -4​

Answer 1

Step-by-step explanation:

3x+x/y-y²

We have x=6 ans y= -4

3×6+6/-4-4²

18+6/-4+16

24/12

2/1

Answer 2

Following are the step for getting the answer :

Given:

$3x+\frac{x}{y} -y^2$

x=6 and y= -4

To find:

simplification $3x+\frac{x}{y} -y^2$

Solution:

we have to simplify the given expression

given that,

x=6 and y=-4

so, put the value of x=6 and y=-4 in  the

$3x+\frac{x}{y} -y^2$

we get,

$3\times 6+\frac{6}{-4} -(-4)^2$

we will simplify the expression by BODMAS rule

B  bracket

O  of/order

D  division

M  multiplication

A  addition

S   subtraction

$3\times 6+\frac{6}{-4} -(-4)^2$

$=3\times6+\frac{6}{-4} -16\\\\=18+\frac{6}{-4} -16\\\\=\frac{-72+6}{-4} \\\\=\frac{-66}{-4} -16\\\\=\frac{33}{2} -16\\\\=\frac{33-32}{2}\\\\ =\frac{1}{2}$

thus, the answer is 1/2
