a+b=1,a-b=16

Solution

a + b = 1, a - b = 16

Solution

a = \frac{17}{2}, b = - \frac{15}{2}

Solution steps

[a + b = 1 a - b = 16]

Isolate

a

for

a + b = 1 : a = 1 - b

Substitute

a = 1 - b

[1 - b - b = 16]

Simplify

[1 - 2 b = 16]

Isolate

b

for

1 - 2 b = 16 : b = - \frac{15}{2}

For

a = 1 - b

Substitute

b = - \frac{15}{2}

a = 1 - (- \frac{15}{2})

1 - (- \frac{15}{2}) = \frac{17}{2}

a = \frac{17}{2}

The solutions to the system of equations are:

a = \frac{17}{2}, b = - \frac{15}{2}
