Given the following equation:
![y=2x-5](https://img.qammunity.org/2023/formulas/mathematics/college/h4ql8u0y8s8jahyniqm9lptl39ukm85t0p.png)
1. You know this value of "x" shown in the table:
![x=4](https://img.qammunity.org/2023/formulas/mathematics/college/clnezaiwnjqx862gnqh94au9b279p8untt.png)
Then, you can substitute it into the equation and evaluate, in order to find the corresponding y-value:
![\begin{gathered} y=2(4)-5 \\ y=8-5 \\ y=3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/xnjo8p3an6fcokr83xiydje25ddruqxv7t.png)
2. To find the value of "x" when:
![y=1](https://img.qammunity.org/2023/formulas/mathematics/high-school/dy87pp1e3lz28ku95s9s4tv5bvbrg0dkd1.png)
You have to substitute this value into the equation:
![1=2x-5](https://img.qammunity.org/2023/formulas/mathematics/college/2japu1udzpuyuv5pebti1net8xw6fhy1gv.png)
And solve for "x":
![\begin{gathered} 1+5=2x \\ \\ (6)/(2)=x \\ \\ x=3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/geb0etdlq8ufksne1lkbdl7wlcx4bt5wjq.png)
Therefore, the answer is:
