2/7 (54-x)=x

\frac{2}{7} (54 - x) = x

x = 12

Solution steps

\frac{2}{7} (54 - x) = x

Expand

\frac{2}{7} (54 - x) : \frac{108}{7} - \frac{2}{7} x

\frac{108}{7} - \frac{2}{7} x = x

Move

\frac{108}{7}

to the right side

- \frac{2}{7} x = x - \frac{108}{7}

Move

x

to the left side

- \frac{9}{7} x = - \frac{108}{7}

Multiply both sides by

7

- 9 x = - 108

Divide both sides by

- 9

x = 12

y, 2 y + 8 x = 1

y, 6 x + y = 12

a, 10 a - 4 b = - 5 a + 6 b

x + 5 = 0

25 = 10 + 103 c
