Start the equation by putting the equations equal to each other 3x+14=7x-10
Next +10 on both sides
3x+14=7x-10
+10 +10
You are left with 3x+24=7x
because the 10's canceled each other out.
Next -3x on both sides
3x+24=7x
-3x +3x
You are left with 24= 10x
because like before the 3's canceled each other out
Now you will divide both sides by 10
24=10x
---- -----
10 10
2.4= X is the answer!
These problems really aren't hard just set them equal to each other and see if what they are saying is true. Are they equal? Do they both equal 0?
The answer is A!
Sadie is correct because 3(2x+3y) equals 6x+9y
