Answer:
Option c
Step-by-step explanation:
A system of equations are given to us. And we need to solve them . The given system is
We numbered the equations here . Now put the value of equation 1 in equation 2 that is substituting y = 2x - 3 in eq. 2 .
We got two values of x as 0 & 2 . Alternatively substituting these values we have ,
Thefore the required answer is ,
38/5 is the answer to the question
Answer:
10c - 4d
Step-by-step explanation:
1. Rearrange the problem so similar variables are closer together
3c + 7c + 5d - 9d
2. Simplify the problem by adding like terms
3c + 7c = 10c
5d - 9d = -4d
3. Rewrite the problem so the variables are in ABC order
10c - 4d
Hope this helps :)
