Question 1056223
add 96, 90, 89, 97 and unknown x and divide by 5:
96+90+89+97+x/5 = 92
Do this:
Add all the numbers on the left.
Multiply both sides times 5. On the left, times 5/5 cancel each other and you are left with the sum of the numbers+x On the right you will have the product of 92 times 5.
Now subtract the sum on the left from the number on the right. You'll have the x by itself on the left and your answer on the right.
