Answer:
Hope this will help you
Step-by-step explanation:
it depends on what you believe, butttt i would say science
4/5 - /7 =
4/5 - 2/7
5 * 7 = 35
7 * 4 = 28
5 * 2 = 10
28/35 - 10/35 = 18/35
3(x + 4) = 3(x) + 3(4)3(x + 4) = 3x + 123x + 12 = 3x + 12
Subtract 12 from both sides3x + 12 - 12 = 3x + 12 - 12
3x = 3x3x - 3x = 3x - 3x= 0
