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

The solution for this system of equations is (-3,2)

kifflom [539]

98-x^2=0\qquad\text{add}\ x^2\ \text{to both sides}\\\\98=x^2\to x^2=98\\\\x=\pm\sqrt{98}\\\\x=\pm\sqrt{49\cdot2}\\\\x=\pm\sqrt{49}\cdot\sqrt2\\\\\boxed{x=-7\sqrt2\ \vee\ x=7\sqrt2}
