Hey there!

$\bold{\frac{8(-14)}{(-8)-3(-13)}}$

$\bold{8\times-14=-112}$
$\bold{\frac{-112}{(-8)-3(-13)}}$
$\bold{3\times-13=39}$
$\bold{\frac{-112}{-8-39} }$
$\bold{-8-(-39)=31}$
$\boxed{\boxed{\bold{Answer:\frac{-112}{31}}}}$

Good luck on your assignment and enjoy your day!

Solve by the linear combination method (with or without multiplication).

Dima020 [189]

The first step is to name the equations to make the process of solving them easy.

$6x+7y=-4....(1)\\5x-3y=-21....(2)$

The second step is to multiply each of the equations by the coefficient of the x term in the other equation. In this case, we will multiply equation (1) by 5 to get equation (3) and then multiply equation (2) by 6 to get equation (4).

$-30x-35y=20...(3)\\30x-18y=-126...(4).$

The next step is to add equation equation(3) and (4) together to get equation (5) as shown below;

$-53y=-106....(5)\\=> y= 2.$

The next step is to take the value of y and substitute it into any of the equations above. For this solution, I pick equation (1). The work done to solve for x is shown below.;

$6x+7y=-4\\=>6x+7(2)=-4\\=>6x=-18\\=>x=-3$
