4x+y=1,4x-2y=10

Solution

4 x + y = 1, 4 x - 2 y = 10

Solution

x = 1, y = - 3

Solution steps

[4 x + y = 1 4 x - 2 y = 10]

Isolate

x

for

4 x + y = 1 : x = \frac{1 - y}{4}

Substitute

x = \frac{1 - y}{4}

[4 \cdot \frac{1 - y}{4} - 2 y = 10]

Simplify

[1 - 3 y = 10]

Isolate

y

for

1 - 3 y = 10 : y = - 3

For

x = \frac{1 - y}{4}

Substitute

y = - 3

x = \frac{1 - ( - 3 )}{4}

\frac{1 - ( - 3 )}{4} = 1

x = 1

The solutions to the system of equations are:

x = 1, y = - 3

Popular Examples

y= 4/5 x+8,2x+y=-6

y = \frac{4}{5} x + 8, 2 x + y = - 6

3x+4y=-1,3x-y=3

3 x + 4 y = - 1, 3 x - y = 3

2x+3y+b=0,4x=3y

2 x + 3 y + b = 0, 4 x = 3 y

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

x + y = 9, x - y = 5
