Answer:
x= - 50/9
Step-by-step explanation:
multipy both equations by 12
9x+60=10
then move the constant to the right hand side and change it's sign
9x= 10 - 60
calculate difference
9x = -50
divide both sides by 9
x= - 50/9
It is 9 because all the other numbers are in the 80s and 90s 9 is way to low.
10^4 = 10,000
9 x 10,000 = 90,000
It’s the first one.............
