Answer:
B
Step-by-step explanation:
first make each equation 'y='.
then if you times each x value by each other it has to equal '-1'.
so for B, itll be y=1/3x-11/3 and y=-3x+23.
1/3 x -3 = -1
Answer:
X= -13
Step-by-step explanation:
The goal is to get x by itself!
<em>Rule of thumb: whatever you do to the left, you MUST do to the right</em>
Step 1: Subtract 8 from the left side of the equation (the = sign)
x + 8 = (-5)
- 8 --> this gets x by itself
Step 2: Subtract 8 from (-5) on the right side <em>(because you did it on the left</em>
x = (-5)
- 8
*<em>note: x is now by itself*</em>
Step 3: Solve!
x = (-5) - 8 -13
x = -13
