Solve {l}{y=x^2+5}{x=5+7-88^3-1840}

$$\left\{ \begin{array} { l } { y = x ^ { 2 } + 5 } \\ { x = 5 + 7 - 88 ^ { 3 } - 1840 } \end{array} \right.$$

Solve for y, x

$$x=-683300$$

$$y=466898890005$$

Solution Steps

Consider the second equation. Add 5 and 7 to get 12.

$$x=12-88^{3}-1840$$

Calculate 88 to the power of 3 and get 681472.

$$x=12-681472-1840$$

Subtract 681472 from 12 to get -681460.

$$x=-681460-1840$$

Subtract 1840 from -681460 to get -683300.

$$x=-683300$$

Consider the first equation. Insert the known values of variables into the equation.

$$y=\left(-683300\right)^{2}+5$$

Calculate -683300 to the power of 2 and get 466898890000.

$$y=466898890000+5$$

Add 466898890000 and 5 to get 466898890005.

$$y=466898890005$$

The system is now solved.

$$y=466898890005 x=-683300$$
