Answer:
A numeral is a symbol or name that stands for a number.
Examples: 3, 49 and twelve are all numerals.
So the number is an idea, the numeral is how we write it.
Step-by-step explanation:
Rearranging the first equation:-
3x - 4y = -7
9x + 4y = 139
12x = 132
x = 132/12 = 11
Substituting fro x in the second equation:-
9(11) + 4y = 139
4y = 139 - 99 = 40
y = 40/4 = 10
Answer x = 4 , y = 10.
