What is 4x+12=20
4x+12=20
4x + 12 - 12 = 20 - 12
4x = 8
x = ??
"It" (what you have written) is an equation. If you wanted the solution for x, you should have said so.
To solve the equation 4x + 12 = 20, we can use algebraic techniques to isolate the variable x. Here's how:
Step 1: Start by subtracting 12 from both sides of the equation to get rid of the constant term on the left side:
4x + 12 - 12 = 20 - 12
This simplifies to:
4x = 8
Step 2: Next, we want to isolate the variable x, so divide both sides of the equation by 4:
4x/4 = 8/4
This simplifies to:
x = 2
So, the solution to the equation 4x + 12 = 20 is x = 2.
