Answer:

0

Step-by-step explanation:

First, you need to try to get rid of the ().

To do this:

15 * 3 and 15 * x

This makes 45 and 15x after the = , so the formula is now:

15x + 45 = 45 + 15x

Now get the 15x to the left side. When a number switches sides, it becomes negative when positive and positive when negative. So in this case 15x will become -15x and the 45(on the left) becomes - 45

15x - 15x = 45 - 45

Answer: 0

15x + 45 = 45 + 15x
15x - 15x = 45 - 45
0x = 0 (*)
If we plug any real numbers of x to equation (*) we will always get 0 = 0
So the set of solutions of this question is all real numbers

After the addition of an acid, a solution has a volume of 90 milliliters. The volume of the solution is 3 milliliters greater th
11111nata11111 [884]

Answer: 21.75\ milliliters

Step-by-step explanation:

Let be "x" the original volume of the solution (in milliliters) before the acid was added and "y" the volume of the solution (in milliliters) after the addition of the acid.

Set up a system of equations:

\left \{ {{x+y=90} \atop {y=3x+3}} \right.

Applying the Substitution Method, you can substitute the second equation into the first equation and then solve for "x":

x+y=90\\\\x+(3x+3)=90\\\\4x+3=90\\\\x=21.75
