Question 97200
I'm assuming you want to see if x=-5 makes the equation true or not right?


{{{5x-8x+7=22}}} Start with the given equation



{{{-3x+7=22}}} Combine like terms



{{{-3(-5)+7=22}}} Plug in x=-5



{{{15+7=22}}} Multiply



{{{22=22}}} Add. Since the two sides of the equation are equal, x=-5 is a solution
