Answer: x=−2
Step-by-step explanation: Step 1: Subtract 2x from both sides.
−3x−3−2x=2x+7−2x
−5x−3=7
Step 2: Add 3 to both sides.
−5x−3+3=7+3
−5x=10
Step 3: Divide both sides by -5.
−5x/-5=10/-5
0.125 sorry if I’m wrong :(
For this you would do

Because 60% is the same as 0.60. And solving a problem like this is the opposite of finding a percent of a number. When you solve this you get 80. So there are 80 students in total.
Answer:
x = 2 1/6 (13/6)
Step-by-step explanation:
to solve the proportion you must first find the LCF or least common factor
that is 6
so turn 8/3 into 16/6 by multiplying it by 2/2
x + 3/6 = 16/6
then you subtract 3/6 from both sides
x = 13/6
x is 2 1/6
