Question

given that a = X + 3 ; b = 4 - X and C = X, find the value of 2a + b - c​

Answer 1

Answer:

10

Step-by-step explanation:

2a+b-c

=2(x+3)+4-x-x

2x+6+4-2x

6+4

10

Answer 2

a = x + 3

b = 4 - x

c = x

2a + b - c

= 2(x + 3) + (4 - x) - (x)

= 2x + 6 + 4 - x - x

= 2x + 10 - 2x

= 10

Hence, 2a + b - c = 10
