7x-9137+100^{2}-863-\frac{1}{2}=154
Calculate the square root of 49 and get 7.
7x-9137+10000-863-\frac{1}{2}=154
Calculate 100 to the power of 2 and get 10000.
7x+863-863-\frac{1}{2}=154
Add -9137 and 10000 to get 863.
7x-\frac{1}{2}=154
Subtract 863 from 863 to get 0.
7x=154+\frac{1}{2}
Add \frac{1}{2} to both sides.
7x=\frac{308}{2}+\frac{1}{2}
Convert 154 to fraction \frac{308}{2}.
7x=\frac{308+1}{2}
Since \frac{308}{2} and \frac{1}{2} have the same denominator, add them by adding their numerators.
7x=\frac{309}{2}
Add 308 and 1 to get 309.
x=\frac{\frac{309}{2}}{7}
Divide both sides by 7.
x=\frac{309}{2\times 7}
Express \frac{\frac{309}{2}}{7} as a single fraction.
x=\frac{309}{14}
Multiply 2 and 7 to get 14.
