por favor la necesito para hoy es urgente plisssss

Respuesta:
2x + 3y = 7
3x - 4y = 2
3y = 7 - 2x
y = 7/3 - 2/3x
-4y = 2 - 3x
y = -2/4 + 3/4x
7/3 - 2/3x = -2/4 + 3/4x
7/3 + 2/4 = 3/4x + 2/3x
17/6 = 17/12x
17/6 * 12/17 = x
2 = x
7/3 - 2/3 * 2 = y
1 = y
4x - 3y = 19
5x + 2y = 41
-3y = 19 - 4x
y = -19/3 + 4/3x
2y = 41 - 5x
y = 41/2 - 5/2x
-19/3 + 4/3x = 41/2 - 5/2x
-19/3 - 41/2 = -4/3x - 5/2x
-161/6 = -23/6x
-161/6 * -6/23 = x
7 = x
41/2 - 5/2 * 7 = y
3 = y
3x + 4y = 3
5x - 4y = 37
4y = 3 - 3x
y = 3/4 - 3/4x
-4y = 37 - 5x
y = -37/4 + 5/4x
3/4 - 3/4x = -37/4 + 5/4x
3/4 + 37/4 = 3/4x + 5/4x
10 = 2x
10 * 2 = x
5 = x
-37/4 + 5/4 * 5 = y
-3 = y
x + y = 4
x- y = 2
y = 4 - x
-y = 2 - x
y = -2 + x
4 - x = -2 + x
2 + 4 = x + x
6 = 2x
6/2 = x
3 = x
4 - 3 = y
1 = y
DAME CORONITA PLIS??? :D
