Solve Systems by Substitution x+y=-1 3x-2y=2 and x=y-2 3x-4y=-13
Answers
Problem one: 1.) Isolate one variable of one equation x+y-x=-1-x y=-1-x 2.) Plug in equation for isolated value into other original equation 3x-2(-1-x)=2 3.) Distribute 3x+2+2x=2 4.) Add like terms 5x+2=2 5.) Subtract two from both side 5x=0 6.) Divide both sides by 5 x=0 7.) Plug in numerical value for x into one equation (original or not) 0+y=1 8.) Subtract zero from both sides y=1 For the first problem, the answer is: x=0, y = 1
For the second problem, follow very similar steps: 3(y-2)-4y=-13 3y-6-4y=-13 -y-6=-13 -y=-7 y=7
x=y-2 x=7-2 x=5 That's your answer for the second problem: x=5, y=7
The person buys a total of 20 frames. 'f' of the frames are size 4 by 6, and cost 5.8 that means 20 - f frames are size 5 by 7, and cost 9.6 And the total is 80.8
So... we get:
5.8f + (20-f)9.6 = 80.8
Answer is B
