Write the equation for the following: A number decreased by 30 is the same as 14 minus 3 times the number. Then solve.

number = x

x - 30 = 14 - 3x

now move the like terms to the same side:

x + 3x = 14 + 30

4x = 44

divide by 4

x =11

Let the no. be n.

No. decreased by 30= n-30

14 minus 3 times no.= 14-3n

If we solve it, we get:

n-30=14-3n

n+3n= 14+30

4n= 44

n= 44/4

n=11
