3x = 2(21 + 5x)
To solve the equation 3x = 2(21 + 5x), we’ll start by simplifying both sides of the equation
To solve the equation 3x = 2(21 + 5x), we’ll start by simplifying both sides of the equation.
Let’s distribute the 2 to the terms inside the parentheses:
3x = 2*21 + 2*5x
Now, simplify the right side:
3x = 42 + 10x
Next, let’s isolate the variable terms on one side of the equation. We can do this by subtracting 10x from both sides:
3x – 10x = 42 + 10x – 10x
-7x = 42
To solve for x, we’ll divide both sides of the equation by -7:
(-7x)/(-7) = 42/(-7)
Simplifying:
x = -6
Therefore, the solution to the equation 3x = 2(21 + 5x) is x = -6.
