Question

Solve the following system
b-C= 8
b+ 2C = 5
Your answer

Answer 1

b = 7

c = -1

Explanation:

you can solve the first equation for 'b' to get:

b = 8 + c

now substitute the expression '8+c' for 'b' in the second equation to get:

8 + c + 2c = 5

8 + 3c = 5

3c = -3

c = -1

now solve for 'b':

b = 8 + (-1)

b = 7
