Answer:
Step-by-step explanation:
1) 4x -3
x = -7 ;
4x - 3 = 4*(-7) - 3 = - 28 - 3 = -31
x = 14 ;
4x - 3 = 4*14 - 3 = 56 - 3 = 53
x = 0
4x - 3 = 0 - 3 = -3
2) 6 -3x
x = -7 ;
6 - 3x = 6 - 3*(-7) = 6 + 21 = 27
x = 14
6 - 3x = 6 - 3*14 = 6 - 42 = -36
x = 0
6 - 3x = 6 - 0 = 6
4)
Answer:
the lines represent absolute value bars
Step-by-step explanation:
STEP 1: Move all terms not containing |5−x| to the right side of the equation.
STEP 2: Divide each term by 3 and simplify.
STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.
<em>5-x=±5</em>
STEP 4: Set up the positive portion of the ± solution.
STEP 5: Solve the first equation for x.
STEP 6: Set up the negative portion of the ± solution.
STEP 7: Solve the second equation for x.
NOTE: The solution to the equation includes both the positive and negative portions of the solution.
