4(x + 3) = 7x
To solve the equation 4(x + 3) = 7x, we need to isolate the variable x on one side of the equation
To solve the equation 4(x + 3) = 7x, we need to isolate the variable x on one side of the equation. Here are the steps to solve it:
1. Distribute the 4 to the terms inside the parentheses:
4 * x + 4 * 3 = 7x
4x + 12 = 7x
2. Get all the terms involving x on one side of the equation. To do this, we subtract 4x from both sides of the equation:
4x – 4x + 12 = 7x – 4x
12 = 3x
3. Divide both sides of the equation by 3 to isolate x:
12/3 = 3x/3
4 = x
So, the solution to the equation is x = 4.
In simpler terms, when we substitute x with 4 in the equation 4(x + 3) = 7x, both sides of the equation will be equal.
