Answer:
The main principle of solving equations is to find the unknown value
Step-by-step explanation:
For example:
I hope this helps
The fundamental principle of equation solving is based on the fact that after applying the same operation on both sides of the equation the solutions of the original equation are also solutions of the new equation.
c-120
1900*4%
1900*0.04
76 (interest for a year)
76*3/4 (3/4 because 9 months is 3/4 of a year)
57 (9 months interest)
Margo will pay $57 in interest
the slope is 0
y-intercept is 8
