x+y=4,1x=5+y

Solution

x + y = 4, 1 x = 5 + y

Solution

x = \frac{9}{2}, y = - \frac{1}{2}

Solution steps

[x + y = 4 1 \cdot x = 5 + y]

Isolate

x

for

x + y = 4 : x = 4 - y

Substitute

x = 4 - y

[1 \cdot (4 - y) = 5 + y]

Simplify

[4 - y = 5 + y]

Isolate

y

for

4 - y = 5 + y : y = - \frac{1}{2}

For

x = 4 - y

Substitute

y = - \frac{1}{2}

x = 4 - (- \frac{1}{2})

4 - (- \frac{1}{2}) = \frac{9}{2}

x = \frac{9}{2}

The solutions to the system of equations are:

x = \frac{9}{2}, y = - \frac{1}{2}
