Question - Solving a Linear Equation with One Variable
Solution:
The image shows two systems of equations. The first one is a two-variable linear system, and the y-terms have been eliminated, resulting in a single linear equation -14x = 7.To find the value of x, we need to solve the equation -14x = 7.We do so by isolating x:-14x = 7x = 7 / (-14)x = -1/2Thus, the value of x is -1/2, which corresponds to option A: -1/2.
