3x+4y=20,2x-3y=2

Solution

3 x + 4 y = 20, 2 x - 3 y = 2

Solution

x = 4, y = 2

Solution steps

[3 x + 4 y = 20 2 x - 3 y = 2]

Isolate

x

for

3 x + 4 y = 20 : x = \frac{20 - 4 y}{3}

Substitute

x = \frac{20 - 4 y}{3}

[2 \cdot \frac{20 - 4 y}{3} - 3 y = 2]

Simplify

[\frac{40 - 17 y}{3} = 2]

Isolate

y

for

\frac{40 - 17 y}{3} = 2 : y = 2

For

x = \frac{20 - 4 y}{3}

Substitute

y = 2

x = \frac{20 - 4 \cdot 2}{3}

\frac{20 - 4 \cdot 2}{3} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = 2

2x+7y-3=5,x+4y+6=0

2 x + 7 y - 3 = 5, x + 4 y + 6 = 0

7x-4y=5,3x-2y=1

7 x - 4 y = 5, 3 x - 2 y = 1

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

w(x,z,y)+x+z=5,y+z=8,x+z=2

w (x, z, y) + x + z = 5, y + z = 8, x + z = 2

2 x - y = 2, 2 x + y = 13
