13x-6y=20,7x+4y=18

Solution

13 x - 6 y = 20, 7 x + 4 y = 18

Solution

x = 2, y = 1

Solution steps

[13 x - 6 y = 20 7 x + 4 y = 18]

Isolate

x

for

13 x - 6 y = 20 : x = \frac{20 + 6 y}{13}

Substitute

x = \frac{20 + 6 y}{13}

[7 \cdot \frac{20 + 6 y}{13} + 4 y = 18]

Simplify

[\frac{140 + 94 y}{13} = 18]

Isolate

y

for

\frac{140 + 94 y}{13} = 18 : y = 1

For

x = \frac{20 + 6 y}{13}

Substitute

y = 1

x = \frac{20 + 6 \cdot 1}{13}

\frac{20 + 6 \cdot 1}{13} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 1

5x+3y=18,3x-y=2

5 x + 3 y = 18, 3 x - y = 2

a + b = 3, c + d = 4 a

x - y = 7, 2 x - y = 5

4x+2y=7,3x-5y=-24

4 x + 2 y = 7, 3 x - 5 y = - 24
