-2x - 3y = -7
solve systems of equations by substitution. please give me the step and tips, etc. i am new at this.

Question

anonymous · Answer

So for your y-value sub in 6x-11and solve for x

anonymous · Answer

and don't forget parentheses and distributive law.  you know 
$$y=6x-11$$ so the second equation is 
$$-2x-3(6x-11)=-7$$

anonymous · Answer

what zbay said, replace y by 6x - 11

anonymous · Answer

now solve for x via 
$$-2x-18x+33=-7$$
$$-20x=-40$$
$$x=2$$

anonymous · Answer

replace x by 2 to get 
$$y=6\times 2-11$$
$$y=12-11=1$$

anonymous · Answer

great answer!

anonymous · Answer

thanks for all your help, but i have a question. how did you get -20x = -40? haha sorry but i got lost there. did you subtract 33 and -7?

anonymous · Answer

you get that by combining like terms to simplify both sides before you divide to get x by it's self

anonymous · Answer

ohhh okay.. i see.. thank you so much!~

anonymous · Answer

so the answer is (2,1) right?
