Let's solve this and compare it with the answer you got. Sometimes its less confusing if
you get rid of the fraction at the start. You can do this by multiplying both sides (all terms)
by 4 ... When you do that in the first term on the left side the multiplier 4 cancels with
the denominator 4 and you are left with 3x. The -5 times 4 becomes -20. And on the right side
the 4 times 4 results in 16. So, putting this all together, by multiplying all terms on both
sides by 4 the equation is changed to:
.
.
Get rid of the -20 on the left side by adding 20 to both sides to get:
.
.
Solve for x by dividing both sides by 3 and the answer becomes:
.
.
So the answer is x = 12
.
Let's check the answer by going back to the original equation:
.
.
and substituting 12 for x to get:
.
.
Three-fourths of 12 is 9 so the equation is then:
.
.
This is obviously a correct statement ... 9 minus 5 does equal 4 ... so the answer of
x = 12 is correct.
.
Hope this helps you to understand the problem a little better and helps you to find where you
might have made a mistake.
