The easiest way to solve this would be to solve for b, meaning to push everything to the right side of the equal sign until only b remains on the left.
So:
3(a+b) = 7
divide both sides by 3:
a+b = 7/3
subtract a from both sides:
b = 7/3 - a
Thus the answer is A.
So:
3(a+b) = 7
divide both sides by 3:
a+b = 7/3
subtract a from both sides:
b = 7/3 - a
Thus the answer is A.

Given that 3(a+b) = 7 and we need to find the value of b in terms of a
3(a+b) = 7
=> a+ b = \(\frac{7}{3}\)
=> b = \(\frac{7}{3}\) - a
So, Answer will be A
Hope it helps!
