Try solving the equation 2x + 20 = 12x

x = 2

Step-by-step explanation:

2x + 20 = 12x

First, we have to put our exponent on the same side of our equation

2x + 20 = 12x

-2x            -2x

20 = 10x

Now, we have to divide by 10 on both sides to get our exponent on its own (x)

20 = 10x

÷10   ÷10

2 = x or x =2

Hope this Helps! :)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

well the answer to that is xoxoxo
