<h3>Given equations</h3>
- v + 8w = 4v and - m + 5n = - 2
<h3>Solve the first equation for v</h3>
- v + 8w = 4v
- 4v - v = 8w
- 3v = 8w
- v = 8w/3
<h3>Solve the second equation for n</h3>
- - m + 5n = - 2
- 5n = m - 2
- n = (m - 2)/5
Answer:
(2,-2)
Step-by-step explanation:
The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.
-3x+4 = 4x-10
-3x-4x+4-4 = 4x-4x-10-4
-7x = -14
-7x/-7 = -14/-7
x = 2
Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.
y = 4(2)-10
y = 8-10
y = -2
Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)
