8-((10)/((18+R))*R)=0

8 - (\frac{10}{( 18 + R )} \cdot R) = 0

R = 72

Solution steps

8 - (\frac{10}{( 18 + R )} R) = 0

Simplify

- (\frac{10}{18 + R} R) : - \frac{10 R}{18 + R}

8 - \frac{10 R}{18 + R} = 0

Multiply both sides by

18 + R

8 (18 + R) - 10 R = 0

Expand

8 (18 + R) : 144 + 8 R

144 + 8 R - 10 R = 0

Add similar elements:

8 R - 10 R = - 2 R

144 - 2 R = 0

Move

144

to the right side

- 2 R = - 144

Divide both sides by

- 2

R = 72

Verify Solutions

Find undefined (singularity) points:

R = - 18

Combine undefined points with solutions:

R = 72

\frac{8}{x} = \frac{2}{6}

\frac{21}{2 x} = \frac{30}{3 x - 1}

\frac{12}{2 x - 3} = 4

3 (x) + 7 + \frac{24}{x} = 6 x + 7

\frac{0.9764}{1} = \frac{5}{x}
