a+b=1,4a-b=2

Solution

a + b = 1, 4 a - b = 2

Solution

a = \frac{3}{5}, b = \frac{2}{5}

Solution steps

[a + b = 1 4 a - b = 2]

Isolate

a

for

a + b = 1 : a = 1 - b

Substitute

a = 1 - b

[4 (1 - b) - b = 2]

Simplify

[4 - 5 b = 2]

Isolate

b

for

4 - 5 b = 2 : b = \frac{2}{5}

For

a = 1 - b

Substitute

b = \frac{2}{5}

a = 1 - \frac{2}{5}

1 - \frac{2}{5} = \frac{3}{5}

a = \frac{3}{5}

The solutions to the system of equations are:

a = \frac{3}{5}, b = \frac{2}{5}
