Respuesta :
2x + 3y = 13
(3)12x -3y = -6
14x = 7
x = 1/2
2(1/2) = 1
1 + 3y = 13
3y = 12
y = 4
Your answer is : (1/2, 4)
(3)12x -3y = -6
14x = 7
x = 1/2
2(1/2) = 1
1 + 3y = 13
3y = 12
y = 4
Your answer is : (1/2, 4)
Answer:
x = 1/2 and y = 4
Step-by-step explanation:
2x + 3y =13
4x - y = -2
first multiply the second equation by 3, to eliminate y
12x - 3y = -6
eliminate
2x + 3y =13
+ 12x - 3y = -6
= 14x = 7
x = 7/14 or 1/2
sub x into second equation
4x - y = -2
4(1/2) - y = -2
2 - y = -2
subtract 2
-y = -4
y = 4
