a+b=8,a-b=2

Solution

a + b = 8, a - b = 2

Solution

a = 5, b = 3

Solution steps

[a + b = 8 a - b = 2]

Isolate

a

for

a + b = 8 : a = 8 - b

Substitute

a = 8 - b

[8 - b - b = 2]

Simplify

[8 - 2 b = 2]

Isolate

b

for

8 - 2 b = 2 : b = 3

For

a = 8 - b

Substitute

b = 3

a = 8 - 3

Simplify

a = 5
