Step-by-step explanation:
=1/2x - 5 + 2/3x = 7/6 + 4
(1/2 and 2/3 are like terms so we can add them. Next we have to find the lcm)
= lcm is 6 so now we make the denominators same and add them up
= 3+4/6x - 5 = 7/6 + 4
= 7/6x - 5 = 7/6 + 4
Now we do the same to the other side- find lcm and add them
= 7/6x - 5 = 14+48/ 12
= 7/6x -5 = 62/12
Now we bring 5 from the left to the right
= 7/6x = 62/12 + 5
Now we find the lcm again and add them
= 7/6x = 62+60/12
= 7/6x= 122/12
Now we bring the number in the lhs to rhs
= x= 122/12 divided by. 6/7
= x = 122/12 multiplied by 7/6
= x= 11.86
