Solve 3x - 2y = 10 and x + 3y = 7 simultaneously
...Solve 3x - 2y = 10 and x + 3y = 7 simultaneously
x = -4 and y = 1
x = -1 and y = -4
x = 1 and y = 4
x = 4 and y = 1
Correct answer is D
3x - 2y = 10 - - x 3
x + 3y = 7 ---x 2
------------------------
9x - 6y = 30
2x + 6y = 14
-------------------------
11x114411
x = 4
From x + 3y = 7
3y = 7 - 4
3y3 = 33
y = 1
