If x + 3y = 7 and x - 3y =7 , then find y<br><br> Please help me

telo118 [61]

Answer:

$x + 3y = 7 , x - 3y = 7 : y = , x = 7$

Step-by-step explanation:

$\left[\begin{array}{ccc}x + 3y = 7\\x - 3y = 7\end{array}\right]$

Isolate $x$ for $x + 3y = 7 : x = 7 - 3y$ :

Substitute $x = 7 - 3y$ :

$\begin{bmatrix}7-3y-3y=7\end{bmatrix}$

Isolate $y$ for $7 - 3y - 3y = 7 : y = 0$ :

For $x$ $=7-3y$

Substitute $y = 0$

$x=7-3 * 0$

$7 - 3 * 0 = 7$

$x = 7$

The solution to the system of equations are:

$y=0,\:x=7$

Hope I helped. If so, may I get brainliest and a thanks?
