<u>STEPS:</u>
1) set up an equation. use x as a variable
2x + 3x = 25
2) solve the equation for x:
5x = 25
x = 5
3) Now that you know the value of x, substitute it into the expression for how any girls there are, which is "3x" (since the ratio of BOYS to GIRLS is 2:3):
3x
= 3(5)
= 15
So 15 is your answer, and there are <u>15 girls in the class.</u>
-6 + 5x = 6x - 7 Subtract 5x from both sides
-6 = x - 7 Add 7 to both sides
1 = x Switch the sides to make it easier to read
x = 1
