@campbell_st 
Can you help me with this one please?

anonymous · Answer

I need help on all the Parts..

campbell_st · Answer

rewrite the 1st equation with 6y as the subject

6y = 12 - 3x

divide the equation by 3

2y = 4 - x

substitute into the 2nd equation

9x +( 4 -x) = -24

solve for x

the solution will be the point of intersection of the 2 lines

anonymous · Answer

what would the solutions be? @campbell_st

campbell_st · Answer

well you need to solve 

8x + 4 = -24 to find x

anonymous · Answer

I got x = 7/2

anonymous · Answer

I don't think that is right though

anonymous · Answer

nvm i got it

campbell_st · Answer

actually x = -7/2

campbell_st · Answer

and it is the correct value for the equations in your question
