Oksi-84 [34.3K]

Answer:

-35/6

Step-by-step explanation:

We need to find the value of x , And the given pair of Rational numbers are equal.

Question (I) :-

→ 3/4 = 7/x

→ 7/x = 3/4

→ 1/x = 3/4 × 1/7

→ 1/x = 3/28

→ x = 28/3

Question (ii) :-

→ x/7 = -5/6

→ x = -5/6 × 7

→ x = -35/6

<h3>• Hence the value of x is -35/6 .</h3>

The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.

natta225 [31]

we have

$2x-2y=6$ ------> equation $1$

$4x+4y=28$ ------> equation $2$

Multiply by $2$ the equation $1$

$4x-4y=12$ ------> equation $3$

Sum equation $2$ and equation $3$

$4x+4y=28\\ 4x-4y=12\\ ------\\ 8x=40\\ x=40/8\\ x=5$

Substitute the value of x in the equation $2$

$4x+4y=28$

$4*5+4y=28\\ 4y=28-20\\ 4y=8\\ y=8/4\\y=2$

therefore

the answer is the option B

$(5,2)$
