Solve each system using substitution x=-2y=1 x=y-5
Answers
You solve either one for y,but I chose the second one. Add 5 to both sides and you get X+5=y Plug this in to the first equation X=-2(x+5)+1 I am assuming that is plus one instead of equal since the keys are near each other on a phone. Back to the math: use the distributive property to get X=-2x-10+1 now combine terms X=-2x-9 Add 2x to both sides to get 3x=9 Divide both sides by 3 to get X=3 Now plug 3 in as x in any of the above I will choose the second one again So 3=y-5 subtract 5 from both sides to get Y=8 So the solution is (3,8)
