Question

how to simplify 5(x-3)​

Answer 1

Step-by-step explanation:

5(x-3)=0

5x-15=0

5x=15

x=15/5

x=3

Answer 2

Answer:

multiply x-3 (the whole thing) by 5, since x-3 is in brackets and 5 is just outside. You may be wondering why do we multiply 5 and (x-3). Good question. We multiply 5 and (x-3) since there is no sign between  5 and (x-3), (and when I say 'sign', I mean +, -, ÷, x, etc) it is understood that we have to multiply. hence,

The answer is = 5(x-3)​ = 5x - 15

Hope this helps you...
