solvefor x,f-1(3)=2 x/5-1

solve for

x, f - 1 (3) = 2 \frac{x}{5} - 1

x = \frac{5 f - 10}{2}

Solution steps

f - 1 \cdot (3) = 2 \cdot \frac{x}{5} - 1

Switch sides

2 \cdot \frac{x}{5} - 1 = f - 1 \cdot 3

Move

1

to the right side

2 \cdot \frac{x}{5} = f - 2

Refine

2 \cdot \frac{x}{5} : \frac{2 x}{5}

\frac{2 x}{5} = f - 2

Multiply both sides by

5

2 x = 5 f - 10

Divide both sides by

2

x = \frac{5 f - 10}{2}

u, - 3 a - 2 c + 3 u = 6

\frac{( x + 1 )}{2} - 6 + \frac{( 1 - x )}{5} = \frac{7}{10}

x, 4 y + 9 x = 295

(x + 2) - (x + 6) = 10

a, - 3 a - b = 1
