Answer:
The value of the 3 in 63 is 3 ones 1+1+1
Step-by-step explanation:
The reason for this is because it is in the ones place
look at the attachment......
y = 1
x = -3
9x + 2y = 3
-x - y = -12 (multiply second equation with 9)
-9x - 9y = - 108 (add these to up)
-7y = -105
y = 15 use this to find x
9x + 2y ➡ 9x + 30 = 3 ➡ 9x = -27 ➡ x = -3
