solved each equation. Each solution is an integer. The expression were given is nine a minus seven is equal to 29. So our first step is going to be trying to isolate the variable on one side. And in order to do so, you want to do it by adding 70 both sides. So we get nine A is equal to 36 to further isolate only a and get rid of the coefficient of a We want to get rid of nine. So we want to divide by nine. So by dividing my night, we get Hey is you go to 36 over nine, which means A is equal to four.
