x/(10)+y/5+1=1,5 x/8+y/6 =15

\frac{x}{10} + \frac{y}{5} + 1 = 1, 5 \frac{x}{8} + \frac{y}{6} = 15

x = \frac{360}{13}, y = - \frac{180}{13}

Solution steps

[\frac{x}{10} + \frac{y}{5} + 1 = 1 5 \cdot \frac{x}{8} + \frac{y}{6} = 15]

Isolate

x

for

\frac{x}{10} + \frac{y}{5} + 1 = 1 : x = - 2 y

Substitute

x = - 2 y

[5 \cdot \frac{- 2 y}{8} + \frac{y}{6} = 15]

Simplify

[- \frac{13 y}{12} = 15]

Isolate

y

for

- \frac{13 y}{12} = 15 : y = - \frac{180}{13}

For

x = - 2 y

Substitute

y = - \frac{180}{13}

x = - 2 (- \frac{180}{13})

- 2 (- \frac{180}{13}) = \frac{360}{13}

x = \frac{360}{13}

The solutions to the system of equations are:

x = \frac{360}{13}, y = - \frac{180}{13}

(1) x = 7, 3 x + y = 25

2 x - 3 y = - 15, 3 x - 4 y = - 18

\frac{4}{x} + \frac{3}{y} = 1, \frac{3}{x} - \frac{2}{y} = \frac{1}{24}

x + 2 y - 3 z = 11, 2 x + y - 2 z = 9, 4 x + 3 y + z = 16

5 x - y = 9, 2 x + 4 y = 8

What is x/(10)+y/5+1=1,5 x/8+y/6 =15 ?
The solution to x/(10)+y/5+1=1,5 x/8+y/6 =15 is x= 360/13 ,y=-180/13
