Answer:
x = -4 and y = 7
Explanation:
We have to solve the pair of the equation with two variables x and y.
The equations are -7x - 2y = 14 ......(1), and 6x + 6y = 18 ........ (2).
We can use simple algebra to get the solution.
Equation (2) can be written as x + y = 3, ⇒ x = 3 - y ...... (3)
Now, substituting value of x to the equation (1), we get -7(3 - y) - 2y = 14
⇒ 5y = 35
⇒ y = 7.
And from equatio (3), we get x = 3 - y = 3 - 7 = - 4.
Therefore, the solution of the given equations is x = -4 and y = 7. (Answer)
