To solve this question you need to cross multiply

So first do 3(2x+1) = 4(3x-2)
Which gives you 6x+1 = 12x-8

Now you solve it like a normal equation
6x+1 = 12x-8
9 = 6x
3/2 = x

2x + 6y = -2<br> -x + 2y = 6<br> By elimination method
Anna007 [38]

Answer:

 x = -4 ;  y = 1

Step-by-step explanation:

2x + 6y = -2   --------(i)

-x + 2y = 6     --------(ii)

            2x + 6y = -2

(ii)*2  <u>   -2x + 4y = 12</u>

add;              10y = 10

                        y = 10/10

                       y = 1

Substitute y in (i)

2x + 6*1 = -2

2x +6= -2

2x = -2-6

2x = -8

x = -8/2

x = -4
