Solve x=117*9.0-13*9^2/2

$$x = 117 \times 9.0 - 13 \times 9 ^ { 2 } / 2$$

Solve for x

$$x = \frac{1053}{2} = 526\frac{1}{2} = 526.5$$

Steps for Solving Linear Equation

Multiply 117 and 9 to get 1053.

$$x=1053-\frac{13\times 9^{2}}{2}$$

Calculate 9 to the power of 2 and get 81.

$$x=1053-\frac{13\times 81}{2}$$

Multiply 13 and 81 to get 1053.

$$x=1053-\frac{1053}{2}$$

Convert 1053 to fraction \frac{2106}{2}.

$$x=\frac{2106}{2}-\frac{1053}{2}$$

Since \frac{2106}{2} and \frac{1053}{2} have the same denominator, subtract them by subtracting their numerators.

$$x=\frac{2106-1053}{2}$$

Subtract 1053 from 2106 to get 1053.

$$x=\frac{1053}{2}$$

Assign x

$$x≔\frac{1053}{2}$$
