How many solutions does an equation have when you isolate the variable and it equals constant?
As many solutions as there are points in the domain.
Which property would be use to isolate the variable j in this equation 7j equals 49?
You would use several properties. The first is that performing the same operation to both sides of an equation is valid. Next the multiplicative inverse property of 1/7 (with respect to 7).
How could you isolate the variable g in this equation g - 6 equals 12?
g - 6 = 12In order to isolate the variable 'g' you must add 6 to both sides of the equation.In algebra, you must perform the opposite operation of the one presented in the problem. For example, the equation above has "minus 6". The opposite opporation for subtraction is addition. So in this case you must ADD 6 to both sides of the equation. Performing the operation to both sides of the equation is essentially multiplying the entire equation by 1, and any time you multiply something by 1 you get the same thing. Because of this, adding to both sides of the equation does not change the final answer.So..g - 6 = 12+6 +6g = 18
