Question

Help determine whether each equation is an identity or whether it has no solution

Pls & thank you

Answer 1

27. 2(a - 4) = 4a - (2a + 4)

2a - 8 = 2a - 4

this is impossible so No solution.

31. -6a + 3 = - 3(2a - 1)
-6a + 3 = -6a + 3

Both sides are identical so this is an Identity.

Answer 2

27)
2(a-4)=2a-8
4a-(2a+4)=4a-2a-4=2a-4
2a-8 is not equal to 2a-4
31
-6a+3
-3(2a-1)=-3*2a-(-3)(1)=-6x+3
-6a+3=-6a+3 so it's an identity
