Isolate the variable by dividing each side by factors that don't contain the variable. This will give you the answer below:
X = 2 = Answer D
Answer:
D. 2
Step-by-step explanation:
One way by solving the equality:
[tex]////// 9x - 10 = 3x + 2////// 9x - 10 + 10 = 3x +2 + 10////// 9x - 3x = 3x + 12 - 3x////// 6x = 12///// 6x/6 = 12/6x = 2[/tex]
I can't put each on a line (the site isn't allowing it), so the //// means it goes to another line.
Another way is by replacing x by each of the possible solutions and see which makes the equality true.
