5x-2y=4,3x+4y=18

Solution

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

Solution

x = 2, y = 3

Solution steps

[5 x - 2 y = 4 3 x + 4 y = 18]

Isolate

x

for

5 x - 2 y = 4 : x = \frac{4 + 2 y}{5}

Substitute

x = \frac{4 + 2 y}{5}

[3 \cdot \frac{4 + 2 y}{5} + 4 y = 18]

Simplify

[\frac{12 + 26 y}{5} = 18]

Isolate

y

for

\frac{12 + 26 y}{5} = 18 : y = 3

For

x = \frac{4 + 2 y}{5}

Substitute

y = 3

x = \frac{4 + 2 \cdot 3}{5}

\frac{4 + 2 \cdot 3}{5} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 3

7x-2y=9,4x+6y=15

7 x - 2 y = 9, 4 x + 6 y = 15

6x-5y=-9,4x+3y=13

6 x - 5 y = - 9, 4 x + 3 y = 13

x + y = 5, x - y = 7

x + y = 2, 2 x - y = 1

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