When solving by substation the answer would be: X= 1 , y= 5
Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables
A) John: 3.75+1.45m
Kiara: 6.25+0.55m
B) (3.75+1.45m)+(6.25+0.55m)
Added: 10+2m
C) (10+2m) divide by 2
Factored: 5+m
When you add integers, you keep the sign on the sum.
For example:
-9 + -9 = -18 (kept the sign)
9 + 9 = 18 (kept the "sign")
It is in the thousands place.
