Question

Solve for x. 2.8 3.2x + 1 = 16.6

Answer 1

Answer:

$\sf x = \dfrac{15.6-2.8a}{3.2}$

Step-by-step explanation:

Solve for 'x'.

To solve for 'x', isolate 'x'.

 2.8a + 3.2x + 1 = 16.6

Subtract 1 from both sides.  {Subtraction property of equality}

   2.8a + 3.2x = 16.6 - 1

    2.8a + 3.2x = 15.6

Subtract 2.8 a from both sides.

              3.2x  = 15.6 - 2.8a

Now, divide both sides by 3.2.  {Division property of equality}

                 $\sf \dfrac{3.2x}{3.2}=\dfrac{15.6-2.8a}{3.2}\\\\\boxed{x=\dfrac{15.6-2.8a}{3.2}}$
