Answer:
a) 5x/16
b) x = 32
Explanation:
a) x/8 + 3x/16 can be simplified by getting a common denominator. x/8 can be changed like this:
x/8 × 2/2 is 2x/16
now we have:
2x/16 + 3x/16
= 5x/16
b) solve x/8+3x/16=10
change the left side of the equation as in part a.
5x/16 = 10
multiply both sides of the equation by 16
5x = 160
divide by 5
x = 32
