The value of x in the equation x + 7 = 12 is 5, obtained through algebraic operations that preserve the equality of the equation.
To determine the value of x in the equation x + 7 = 12, we follow a simple algebraic process to isolate x.
Subtract 7 from both sides of the equation:
x = 12 - 7
Simplify the right side:
x = 5
So, the solution to the equation is x = 5. This means that when you substitute x with 5 in the original equation, it satisfies the equality: 5 + 7 = 12.
In the given equation, x represents an unknown value. The process of solving the equation involves manipulating its terms to isolate x on one side. Subtracting 7 from both sides helps isolate x, revealing that x equals 5.
Understanding and solving equations is fundamental in mathematics, providing a systematic way to find unknown values. In this case, the solution x = 5 ensures that the equation is balanced, demonstrating the principle that what is done to one side of the equation must be done to the other to maintain equality.
