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

Answer: 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.

Let's solve your equation step-by-step.

10x+12=5x+45

Step 1: Subtract 5x from both sides.

10x+12-5x=5x+45-5x

5x+12=45

Step 2: Subtract 12 from both sides.

5x+12-12=45-12

5x=33

Step 3: Divide both sides by 5.

5x/5=33/5 (5x over 5 = 33 over 5)

x=33/5 (x is equal to 33 over 5)
