15x+20y=220,8x+20y=192

15 x + 20 y = 220, 8 x + 20 y = 192

x = 4, y = 8

Solution steps

[15 x + 20 y = 220 8 x + 20 y = 192]

Isolate

x

for

15 x + 20 y = 220 : x = \frac{4 ( - y + 11 )}{3}

Substitute

x = \frac{4 ( - y + 11 )}{3}

[8 \cdot \frac{4 ( - y + 11 )}{3} + 20 y = 192]

Simplify

[\frac{28 y + 352}{3} = 192]

Isolate

y

for

\frac{28 y + 352}{3} = 192 : y = 8

For

x = \frac{4 ( - y + 11 )}{3}

Substitute

y = 8

x = \frac{4 ( - 8 + 11 )}{3}

\frac{4 ( - 8 + 11 )}{3} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = 8

3 x - y = 1, 4 - 2 x + 3 y = 14

3 \cdot (- y) = 1, 2 \cdot + y = 9

2 x - 3 y = 10, 0.4 - y = 10

3 x - 4 y = 41, 11 x + 6 y = 47

x + 3 y = 13, 3 x + y = 7
