Someone please answer<br> 2.1 ( x + 5 ) = 7
tatuchka [14]
Since we have the 2.1 next to the parenthesis, we need to first distribute.

2.1 * x  &   2.1 * 5

2.1x + 10.5

Then we take that and add the equals seven to the problem to move onto the next step.

2.1x + 10.5 = 7

We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.

2.1x + 10.5 = 7
       - 10.5   -10.5

2.1x = -3.5

To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.

2.1x = -3.5
/2.1     /2.1

x = 1.66666666667

Hope this helped!
