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

Solution

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

Solution

x = \frac{7}{2}, y = \frac{3}{2}

Solution steps

[x - y = 2 x - 5 y = - 4]

Isolate

x

for

x - y = 2 : x = 2 + y

Substitute

x = 2 + y

[2 + y - 5 y = - 4]

Simplify

[2 - 4 y = - 4]

Isolate

y

for

2 - 4 y = - 4 : y = \frac{3}{2}

For

x = 2 + y

Substitute

y = \frac{3}{2}

x = 2 + \frac{3}{2}

2 + \frac{3}{2} = \frac{7}{2}

x = \frac{7}{2}

The solutions to the system of equations are:

x = \frac{7}{2}, y = \frac{3}{2}

3 x + 2 y = 2, x + 3 y = 10

2x-4y+6z=16,3x+5y-2z=13,4x-2y-3z=-10

2 x - 4 y + 6 z = 16, 3 x + 5 y - 2 z = 13, 4 x - 2 y - 3 z = - 10

b = 600, a = 10

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

a = 1, b = 2
