This math topic focuses on finding the x-intercept of linear equations presented in standard form and involving decimals. Each question provides a linear equation and multiple-choice answers, affirming skills in manipulating equations to isolate and solve for the variable 'x'. Topics covered include understanding and utilizing the standard form of linear equations (Ax + By = C), calculating intercepts, and working with decimal calculations. Overall, these problems help reinforce linear equation concepts and their graphical interpretations, specifically in pinpointing where a line intersects the x-axis.
