I think it would be 14b  35 +3 = 10 so, 14b38=10 14b=48

yes what merp has shown is correct, but do u understand it? 1) Always expand out the brackets first. then collect like terms and rearrange to solve for your unknown.

the figure is right but it's not exactly 3, can you see that 14 is not a factor of 48? so it can't be a whole number.

7(2b – 5) + 3 = 10 expand brackets. 14b  35 + 3 = 10 collect like terms. 14b 32 = 10 bring 32 over to RHS 14b = 10+32 14b = 42 solve for b using inverse of operation 14 times b = 42 b = 42 divided by 14
