Given : The sum of three times x and 10 is 13
To Find : Correct option
a)3x+10=13
b)3x+13=10
c)3x-10=13
d)none of these
Solution:
The sum of three times x and 10 is 13
three times x is 3x
The sum of three times x and 10
is 3x + 10
The sum of three times x and 10 is 13
=> 3x + 10 = 13
you subtract 3 from 6 times a number, you got 9
=> 6x - 3 = 9
One fourth of n is 3 more than 2
=> n/4 - 2 = 3
One third of a number plus 2 is 3
m/3 + 2 = 3
Taking away 5 from x gives 10
x -5 = 10
Four times a number P is 8
4P = 8
Add 1 to three times n to get 7
=> 3n + 1 = 7
