What needs to be done next?' v After doing this, you will now have ' v You tell your friend to remember that substitution means to replace. So we are replacing ' v ' with ' v '. Final answer is| v ' What is the mistake below? Solve the system equations by substitution: c - y = 20 2x - 2y = 10 Step 1: Rearrange the first equation for y since the y variable has a coefficient of 1. 4x - y = 20 -y = -4x + 20 y = 4x - 20 Step 2: Substitute 4x - 20 in for y in the second equation. -2x - 2y = 10 -2x -(4x - 20) = 10 -2x - 4x + 20 = 10 -6x = -10 x = 5/3 Step 3: Plug 5/3 in for x in either equation to get y. The error is in: O Step 1. 4x should have been added to both sides. O Step 1: It should be y = -4x - 20. O Step 2: The negative is only being distributed to the 4x. O Step 2: (4x - 20) should be multiplied by -2 since it was -2y and (4x - 20) only replaces the y. O Step 3. The x value can only be plugged into the second equation.POSSIBLE POINTS: 4 Which of the following is set up nicely for elimination? :5 o{y 5$+4y= 20 6$+8 : 22 o{ '9 3225 O{5m+10y: 8 5x+4y= 20 POSSIBLE POINTS: 4 . 2m + 7y = 2 . . . . . . . . In solvmg by using elimination, you could eliminate the x variable In one step by 4:13 + 33; = 10 multiplying the first equation by O -2. This would change it to -4x - 14y = 4 O -2. This would change it to -4x -14y = -2 O 4. This would change it to 8x + 28y = -8 O -1. This would change it to -2x - 7y = 2
