The steps taken to solve this system of equations would first be:
1. Sub 4x-2 into your first equation, 2x+5(4x-2)= 12 ->
2. Solve/simplify this equation to get x=1
3. Sub x=1 into your second equation and solve for y = 2
4. Get the solution (1,2)

Answer:
See proof below
Step-by-step explanation:
Assume that V is a vector space over the field F (take F=R,C if you prefer).
Let . Then, we can write x as a linear combination of elements of s1, that is, there exist and such that . Now, then for all we have that . In particular, taking with we have that . Then, x is a linear combination of vectors in S2, therefore . We conclude that .
If, additionally then reversing the roles of S1 and S2 in the previous proof, . Then , therefore .
