4x-5y-20=0,3x+5y-15=0

4 x - 5 y - 20 = 0, 3 x + 5 y - 15 = 0

x = 5, y = 0

Solution steps

[4 x - 5 y - 20 = 0 3 x + 5 y - 15 = 0]

Isolate

x

for

4 x - 5 y - 20 = 0 : x = \frac{5 y + 20}{4}

Substitute

x = \frac{5 y + 20}{4}

[3 \cdot \frac{5 y + 20}{4} + 5 y - 15 = 0]

Simplify

[\frac{35 y + 60}{4} - 15 = 0]

Isolate

y

for

\frac{35 y + 60}{4} - 15 = 0 : y = 0

For

x = \frac{5 y + 20}{4}

Substitute

y = 0

x = \frac{5 \cdot 0 + 20}{4}

\frac{5 \cdot 0 + 20}{4} = 5

x = 5

The solutions to the system of equations are:

x = 5, y = 0

x + y = 14, 2 x + 2 y = 8

2 x + 3 y = 8, 7 x - 3 y = 1

(\frac{1}{x} - y) + (\frac{1}{x} + y) = 6, (\frac{1}{x} - y) - (\frac{1}{x} + y) = 4

2 x - y = 4, - 6 x + 3 y = 18

(1) 2 x + 3 y = 1, 3 x - y = 7
