Question

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

Answer 1

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

$(5,2)$
