Solve each system substitution 6x - 12y=24 And -x - 6y=4

1 answer:

4 0

6x-12y=24
x=-6y-4
6(-6y-4)-12y=24
-36y-24-12y=24
-48y=48
y=-1
6x-12(-1)=24
6x+12=24
6x=12
x=2

6(2)-12(-1)=24
12+12=24
24=24 true
and
-(2)-6(-1)=4
-2+ 6=4
4=4 true

VMariaS [17]

Step-by-step explanation:

<h3>★ Solution:-</h3>

$\sf \leadsto \dfrac{7x - 3}{5x - 2} = -2$

$\sf \leadsto 7x - 3 = -2(5x - 2)$

$\sf \leadsto 7x - 3 = -10x + 4$

$\sf \leadsto 7x + 10x = 4 + 3$

$\sf \leadsto 17x = 7$

$\sf \leadsto x = \dfrac{7}{17}$

Hence the value of x is 7/17
