Step-by-step explanation:
18/24>20/24 you have to flip the sign to make it correct
Sig Figs, as they are also known, are important only in Science. But there are three ways you can determine how many sig figs there are. Non-Zero digits are sig figs. Any zeros between two sig figs are significant. (EX: 7008) And, lastly, A final zero(s) in a decimal are significant. (EX: 0.76540800) Last two zeros are significant.
7x + 3y = 30
-2x + 3y = 3....multiply by -1
-----------------
7x + 3y = 30
2x- 3y = -3 (result of multiplying by -1)
----------------add
9x = 27
x = 27/9
x = 3
7x + 3y = 30
7(3) + 3y = 30
21 + 3y = 30
3y = 30 - 21
3y = 9
y = 9/3
y = 3
solution is (3,3)
