Answer:
x = 5
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Isolate the variable, x. Subtract x and 2 from both sides:
-2x (-x) + 2 (-2) = x (-x) - 13 (-2)
-2x - x = -13 - 2
Simplify. Combine like terms:
-2x - x = -13 - 2
-3x = -15
Divide -3 from both sides:
(-3x)/-3 = (-15)/-3
x = -15/-3
x = 5
x = 5 is your answer.

Answer:
25 students
Step-by-step explanation:
Let t= total students
Take the total number of students and multiply by the percent that are boys to get the number of boys
t * 40% = 10
Change to decimal form
t*.40 = 10
Divide by .4 on each side
.40t /.4 = 10/.4
t =25
There are 25 students
