Answer:
Step-by-step explanation:
7 x -5 = 65
7 times what? (x) - 5 equals 65
Well we know that x has to be less than 65 and more than 7 and -5.
So 7 must be multiplied by numbers 8, and up.
7 * 8 -5 = 51, NOT 65.
7 * 9 -5 = 58, NOT 65.
7 * 10 -5 = Does equal 65.
Therefore, x is equivalent to 10.
x=10
7x - 5=65
+5 +5 so the 5's cancel so add 5 to 65
7x =70 because you add 5 to 65 to get 70
7x 7
7 x cancels out so you answer will be
