.75x + 2 = .80x
Now you can find x

5 answers
75/100*x+2=80/100*x
40
can i see my test
75/100x+2=80/100x
3/4x+2=4/5x
2=4/5x-3/4x
Now take LCM of 5 and 4
2 =16x-15x/20
2=x/20
Now divide two by one and x by twenty then multiply both
X=2×20=40 students
3/4x+2=4/5x
2=4/5x-3/4x
Now take LCM of 5 and 4
2 =16x-15x/20
2=x/20
Now divide two by one and x by twenty then multiply both
X=2×20=40 students
