{11x + 6y=47
{2x - 3y = 7
{ - 3x + y = -7

​despejar todo paso a paso

Answer 1

Explicación paso a paso:

a) 2y - 5x = 9

y = 9 + 5x /2

B) 4y + 3x = 12

y = 12 - 3x/4

c) y = 2x

x = y/2

d) x + y = 28

x = 28 - y

e) 3x - 4y = 41

x = 41 + 4y/3

f) 11x + 6y = 47

x = 47 - 6y/11

g) 2x - 3y = 7

x = 7 + 3y/2

h) - 3x + y = -7

y = -7 + 3x
