WebAnswer (1 of 53): If 2X + 3 = 7, then what is the value of x? Well, we can’t answer this, because we have no information about ‘x’; we only have information about another … WebSolve the system and classify. 2 x+y=4 x-y=2 Graphing the two equations we have We see that the point of intersection appears to be (2, 0). If this is the case, then the solution set is Since the solution set consists of a single point, the system is consistent. Note that graphical solutions are approximations. Example 2.

Web1 Answer. Sorted by: 4. Yes. We show that X ⊆ Y, and then Y ⊆ X follows by symmetry. Let x ∈ X. Then { x } ∈ P ( X). So, since P ( X) = P ( Y), have { x } ∈ P ( Y); so x ∈ Y. … Web26 feb. 2015 · This is the same as solving things as usual, note that. $$2x\equiv 1-3y\implies x\equiv 2^{-1}(1-3y)\mod 7$$ modulo $7$, the inverse of $2$ is $4$ since $2\cdot 4\equiv 1\mod 7$, so we get

If we take your approach and add 20 to both sides, look at what happens: 20+20-7x = 6x-6+20. 40-7x = 6x + 14. Nothing has moved across the equals. We've only made the numbers larger than when we started. Hope this helps. bandalier salesWebFind matrices X and Y, if 2X−Y=[ 6−4−62 01] and X+2Y=[ 3−221 5−7].
