Its 19 bro, you substitute 3 into the equation in replace for x
Steps:
First we cross multiply
Then Distribute,
Then move all terms to one side
Factor
Set each factor equal to zero
Answer:
Step-by-step explanation:
y=mx+c
So in this case, m is (-3/7), which is the slope.
(-3/7)(another slope)=-1
Another slope=3/7
A. The slope is -7/3
B. The slope is 3/7
C. The slope is -7/3
D. The slope is -3/7
Thus, the answer is the bottom of the left hand side, which is 3x-7y=14
Hope it helps!!! Good luck!!
Hello there!
First of all, I like your profile picture!
1) There's a lot of different methods for solving a system of equation. But here are my three favorite.
- Graphing
- Substitution (Which I preferred to use and I think it is easier).
- Elimination
2) When solving a system of equations, you can get;
- One solution
- No solution
- Infinite number of solution
3) The graphing method help solving a system of equation by knowing that the solution to a system of equations is the point of intersection of the two lines.
I hope this answer helps. As always, it is my pleasure helping student like you!
