-9x+7=7

Answer:

-9x+7=7 is a simple linear equation that can be solved to find the value of x. Let’s break it down step by step:

1. Subtract 7 from both sides of the equation to isolate the variable: -9x + 7 – 7 = 7 – 7 -9x = 0
2. Divide both sides of the equation by -9 to solve for x: -9x / -9 = 0 / -9 x = 0

Therefore, the solution to the equation -9x+7=7 is x = 0.

Here are a few things to keep in mind about linear equations:

• Linear equations involve only variables raised to the first power (no squared or cubed terms).
• The goal is to isolate the variable on one side of the equation to find its value.
• The same operations must be performed on both sides of the equation to maintain balance.

Example: Let’s consider another equation: -3x + 4 = 10. We can solve it using the same principles:

1. Subtract 4 from both sides: -3x + 4 – 4 = 10 – 4 -3x = 6
2. Divide both sides by -3: -3x / -3 = 6 / -3 x = -2

So, the solution to -3x + 4 = 10 is x = -2.

Remember, when solving linear equations, the ultimate goal is to isolate the variable and determine its value. These equations are used in various fields, such as physics, finance, and engineering, to model and solve real-world problems.
