(34+3x)/(18+x)=2.2

\frac{34 + 3 x}{18 + x} = 2.2

x = 7

Solution steps

\frac{34 + 3 x}{18 + x} = 2.2

Multiply both sides by

18 + x

34 + 3 x = 2.2 (18 + x)

Multiply both sides by

10

340 + 30 x = 22 (18 + x)

Expand

22 (18 + x) : 396 + 22 x

340 + 30 x = 396 + 22 x

Move

340

to the right side

30 x = 22 x + 56

Move

22 x

to the left side

8 x = 56

Divide both sides by

8

x = 7

Verify Solutions

Find undefined (singularity) points:

x = - 18

Combine undefined points with solutions:

x = 7

5 + \frac{z}{z + 2} = 1

\frac{x + 2}{x - 2} = \frac{3}{5}

\frac{40}{x + 1} = 0

x + 7 - \frac{5}{x - 3} = 5

0.14 = \frac{6.4}{R} - 0.2
