5x+128 should be it. 65+75=140. 140-12=128. you can't do anything to the x because they're not common terms so you leave it at that.
Step 1: bring the 1 over to the other side. doing so will give you 3x = -18.
step 2: divide both sides by 3. your answer will be x = -6.
Ratio of girls to boys - 2 : 3 (2+3=5)

623 divided by 5 equals 125.
125 times 2 equals 250.
So, 250 girls are enrolled at Lincoln Middle School.
