The coefficients of x are already opposites, so you can simply add the two equations to eliminate x.
... (-7x +3y) + (7x -2y) = (14) + (-14)
... y = 0 . . . . . . . simplify
... -7x + 3·0 = 14 . . . . substitute the value of x into the first equation
.. x = 14/(-7) = -2
The solution is (x, y) = (-2, 0).
Answer:
x = -45
Step-by-step explanation:
(3/5)x - 15 = (6/5)x + 12
(6/5)x - (3/5)x = -15 - 12
(3/5)x = -27
0.6x = -27
x = (-27)/0.6
x = -45
