You buy 7 books
3b+5=26
*subtract 5 to the 26 side*
3b=21
Now divide 21 by 3
B=7
So there are 7 books bought. ^^
Add Two-thirds to both sides
solution:
x-2/3= 5/6
We have to find how this can be solved for "x" in one step
Remember that,
We we add or subtract same number from both sides of a equation, the equation still remains true
Therefore, from given,
x-2/3=5/6
Add Two-thirds to both sides
x-2/3+2/3=5/6+2/3
x=5/6+2/3
x=9/6
Add Two-thirds to both sides to solve the sum
.65x=39
x=39/.65=60 just solve it as algebra
