3x = 2 (7 + 5x)
To solve the equation 3x = 2(7 + 5x), you need to isolate the variable x
To solve the equation 3x = 2(7 + 5x), you need to isolate the variable x. Here’s how you can do it step by step:
1. Distribute the 2 to the terms inside the parentheses:
3x = 14 + 10x
2. Rearrange the equation by moving the variable terms to one side and the constant terms to the other side:
3x – 10x = 14
3. Combine like terms:
-7x = 14
4. Divide both sides of the equation by -7 to isolate x:
(-7x) / -7 = 14 / -7
5. Simplify:
x = -2
So the solution to the equation 3x = 2(7 + 5x) is x = -2.
