7x-4y=12,5x-3y=6

Solution

7 x - 4 y = 12, 5 x - 3 y = 6

Solution

x = 12, y = 18

Solution steps

[7 x - 4 y = 12 5 x - 3 y = 6]

Isolate

x

for

7 x - 4 y = 12 : x = \frac{12 + 4 y}{7}

Substitute

x = \frac{12 + 4 y}{7}

[5 \cdot \frac{12 + 4 y}{7} - 3 y = 6]

Simplify

[\frac{60 - y}{7} = 6]

Isolate

y

for

\frac{60 - y}{7} = 6 : y = 18

For

x = \frac{12 + 4 y}{7}

Substitute

y = 18

x = \frac{12 + 4 \cdot 18}{7}

\frac{12 + 4 \cdot 18}{7} = 12

x = 12

The solutions to the system of equations are:

x = 12, y = 18

3 x + 4 y = 11, 5 x - 2 y = 1

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

5x+4y=1,2-5x+4y=12

5 x + 4 y = 1, 2 - 5 x + 4 y = 12

3x+2y=7,6x+5y=21

3 x + 2 y = 7, 6 x + 5 y = 21
