Step-by-step explanation:
3 + 2/5 b =11 - 2/5 b (this is the given question is it?)
2/5 b + 2/5 b= 11 - 3 (like terms together, you transpose -2/5b to the other side as shown.)
2b+2b = 8 ( at that stage you would find t
5 hat 5 is the common value to go into 5 itself, as shown.
4b = 8 ( you just add 2b + 2b to have 4b)
5
4b = 8 ( at that point you cross multiply
5 1 as shown)
4b = 8 × 5 ( simple math as shown)
4b = 40 ( you multiply 8 × 5 to obtain 40)
b =10 you can prove that. Thank you.
