Answer 1

Answer:

-(7-10c)/22

Step-by-step explanation:

Isolate a for a - 4b + 2c = 1 : a = 1 + 4b - 2c

Substitute a = 1 + 4b - 2c

[1 + 4b - 2c + 7b - 5c = 8(1 + 4b - 2c) + b - c]

Simplify

[11b - 7c + 1 = 33b - 17c + 8]

b=-

Isolate b for 11b - 7c + 1 = 33b - 17c + 8 : (7 - 10c)/22

For a = 1 + 4b - 2c

Expressing a in terms of c

a = 1 + 4(- (7 - 10c)/22) - 2c

Simplify 1+4(- 7-10c 22 )-2c: (- 2c - 14)/11 + 1

a = (- 2c - 14)/11 + 1

The solutions to the system of equations are: a = (- 2c - 14)/11 + 1, b = - (7 - 10c)/22
