What is the value of x in the equation of 4x + 1.3 = - 7.9

x = -2.3

Step-by-step explanation:

4x + 1.3 = -7.9

First we want to combine the like terms.

Subtract 1.3 from both sides.

4x = -9.2

Now we want to isolate x by dividing both sides by 4.

x = -2.3

Check your answer by plugging x back into the original equation.

4x + 1.3 = -7.9

4(-2.3) + 1.3 = -7.9

Multiply.

-9.2 + 1.3 = -7.9

Add.

-7.9 = -7/9

Your answer is correct.

Hope this helps!

Step-by-step explanation:

4x + 1.3 = - 7.9

4x = - 7.9 - 1.3

4x = - 9.2

x = - 9.2/4

= - 2.3

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
