3. what value of x makes the equation below true?
5x+4 =9x-12

Step-by-step explanation:

Get all the x's to one side and all the non x's to the other. we could do 5x-9x = -12-4.

We get -4x = -16. Then, divide by -4. Dividing two negatives gets a positive. So, -16/-4 = 4

the answer is 4

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

sweetheart, there isn't a cube below.
