Question

"five more than the product of four and a number is

equal to the product of three and that same number
increased by six."
A. X=-1
B. X= 1
C. X= 3
D. X= 1/2

Answer 1

B

Explanation:

Let the number = x

Product: 4 * x

Add 5: 4x + 5

=

3x + 6

Now equate the two parts.

4x + 5 = 3x + 6 Subtract 5 from both sides

4x + 5 - 5 = 3x + 6 - 5 Combine

4x = 3x + 1 Subtract 3x from both sides

4x-3x=3x -3x + 1 Combine

x = 1
