3=(x-60)/2+x/5

3 = \frac{x - 60}{2} + \frac{x}{5}

x = \frac{330}{7}

Decimal Notation

x = 47.14285 \dots

Solution steps

3 = \frac{x - 60}{2} + \frac{x}{5}

Switch sides

\frac{x - 60}{2} + \frac{x}{5} = 3

Multiply by LCM

5 (x - 60) + 2 x = 30

Expand

5 (x - 60) + 2 x : 7 x - 300

7 x - 300 = 30

Move

300

to the right side

7 x = 330

Divide both sides by

7

x = \frac{330}{7}

x, 9 y - 3 x = 18

x, 2 x - 4 y = - 9

2 (4 x - 5) = 3 x - 1

10 x + 2 = - 10 + 8 x

X, X + Y + Z = 1
