Answer:
19
Step-by-step explanation:
12-n/7 = -1
Cross multiply
We have 12-n = -7
Collect like terms
12 + 7 = n
Therefore n = 19
n=91
Explain:
mutiply both sides of the equation by 7: 84-n=-7
move constant to the right and change its sign: -n= -7 - 84
find the diffrence= -n= -91
change the signs: n=91
$143.00
130+10%(13.00)=143.00
