How do you solve for x in this equation? 10x+12=5x+45

x = 6.6

Step-by-step explanation: Since our variable, in this case x, appears on both sides of the equation, we want to put our x terms together on one side of the equation and put our numbers together on the other side of the equation.

So let's put our x's together on the left side of the equation and we do that by subtracting 5x from both sides.

On the left we have 5x + 12 and on the right we have 45.

So rewriting our equation, we have 5x + 12 = 45.

Now we want to put our numbers together on the right side of the equation and we do that by subtracting 12 from both sides.

On the left we have 5x and on the right, 45 - 12 is 33.

So rewriting our equation, we have 5x = 33.

To get x by itself just divide both sides by 5 and we find that x = 6.6.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
