Question

4x-9=31, find the value of 6x

Answer 1

To find the value of x, we must move all of the constant (number) terms to one side of the equation and the variable x to the other side of the equation.

4x - 9 = 31

First, we should add 9 to both sides of the equation so that the -9 cancels out on the left side of the equation.

4x = 40

Next, we should divide both sides of the equation by 4 so that we can cancel out the coefficient of 4 on the variable x.

x = 10

Then, to find the value of 6x, we must substitute in our known value for x into the expression 6x.

6x = 6(10)

To simplify, we should multiply these two numbers together.

60

Therefore, your answer is 60.

Hope this helps!

Answer 2

Here,

4x-9=31

4x=31+9

4x=40

x=40/4

x=10

          so, 6x=6*10 [ x=10 ]

                    = 60
