Variation of equation algebra h/5+0.6=2

Question

In the equation h/5+0.6=2 We can solve by subtracting both side with 0.6 then multiply by 5. 7 will be the answer which is correct. But if we first multiple h/5 with 5 on other side 2*5 we get h+0.6=10 after solving this we get 9.4 wich if we put back in equation is wrong but all rules followed is correct??

Answer 1

you have to multiply the whole left hand side by 5, so you'd get $h+3=10$
