How do i solve x+3y=7

1 answer:

7 0

Answer:

If you're trying to find x or y, you cannot find the exact value since there is one equation. If there was, for example, 2 equations, [a system of equations] you could solve that. But here we only have one equation.

So, if you're trying to solve for x;

x = 7 - 3y

And if you're trying to solve for y;

y = 7/3 - x

(-y+5•3)+7.2y-9)=6.2y+n

kramer

(-y+5x3)+(7.2y-9)=6.2y+n
(-y+15)+(7.2y-9)=6.2y+n
since you're adding the two parentheses, you don't need to have them there
-y+15+7.2y-9=6.2y+n
7.2y-y +15-9 =6.2y+n
6.2y + 6 =6.2y+n
6.2y - 6.2y -n = -6
-n=-6
n=6

check the picture below.

now, if we split that triangle like so with that red line, we can use the right-triangle there, to get θ.

$\bf tan(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{adjacent}{3}}\implies tan(\theta )=1\implies tan^{-1}(\theta )=tan^{-1}(1)\implies \measuredangle \theta =\cfrac{\pi }{4}$
