4x+5y=3,7x-2y=16

Solution

4 x + 5 y = 3, 7 x - 2 y = 16

Solution

x = 2, y = - 1

Solution steps

[4 x + 5 y = 3 7 x - 2 y = 16]

Isolate

x

for

4 x + 5 y = 3 : x = \frac{3 - 5 y}{4}

Substitute

x = \frac{3 - 5 y}{4}

[7 \cdot \frac{3 - 5 y}{4} - 2 y = 16]

Simplify

[\frac{21 - 43 y}{4} = 16]

Isolate

y

for

\frac{21 - 43 y}{4} = 16 : y = - 1

For

x = \frac{3 - 5 y}{4}

Substitute

y = - 1

x = \frac{3 - 5 ( - 1 )}{4}

\frac{3 - 5 ( - 1 )}{4} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = - 1

20x-8y=1,-8x+6y=1

20 x - 8 y = 1, - 8 x + 6 y = 1

-x+5y=10,2x-5y=30

- x + 5 y = 10, 2 x - 5 y = 30
