Question

Four less than three times a number increased by six times the same number is 32

what’s the answer?
-11
-4
—4
-7

Answer 1

Explanation:

Let the unknown number be x;

for Four less than three times a number, it is expressed as (3x-4)

If the number gotten is increased by six times the same number, the equation becomes 3x-4+6x

If they are all equal to 32 then;

3x-4+6x = 32

We are to look for the value of x from the expression;

3x-4+6x = 32

-4+9x = 32

add 4 to both sides

-4+9x+4 = 32+4

+9x = 36

x = 36/9

x = 4

Hence the answer to the unknown number is 4
