Question

rearrange w=(2a+b)-4 to make a the subject

Answer 1

Answer:

distribute the 3: w = 6a + 3b - 4

Move any terms not involving a to the other side: 6a = w - 3b + 4

Divide by 6: a = (w - 3b + 4)/6 or w/6 - b/2 + 2/3

Answer 2

Step-by-step explanation:

Given expression transforms

a = 1/2 ( w + 4 - b )

=> a = 1/2 ( w - b ) + 2
