Answer:
x=2
Explanation:
3x+5=2x+7 this is the original equation
since we have no clue as to what x could be, we just take a guess.
lets say we used 3.
we would plug in 3 where the x's are and get
3(3)+5=2(3)=7
three times three is 9, 9 plus 5 is 14.
2 times 3 is 6, 6 plus 7 is 13.
since these numbers do not match, 3 cannot be the answer.
if you did these same steps with the number two, you would get 11 as the answer for both, therefore, x=2
3(2)+5 2(2)+7
6 +5=11 4+7=11
