20x+25(x-2)+40(x-4)=215

20 x + 25 (x - 2) + 40 (x - 4) = 215

x = 5

Solution steps

20 x + 25 (x - 2) + 40 (x - 4) = 215

Expand

20 x + 25 (x - 2) + 40 (x - 4) : 85 x - 210

85 x - 210 = 215

Move

210

to the right side

85 x = 425

Divide both sides by

85

x = 5

3 x - 4 = 125

3.2 y - 7 = 9

\frac{1}{4} z - \frac{1}{5} = \frac{4}{3} z - \frac{1}{8}

y, - 5 x = 8 - y

x + 9 = - 11
