Adelle solved the equation 4x/7-6=-20 as shown. Fill in the correct justification for each step
yarga [219]

Adelle steps:

\frac{4x}{7} - 6 = -20

\frac{4x}{7}  = -14

4x = -98

x = -24.5

Answer:

See Explanation Below

Step-by-step explanation:

Given

\frac{4x}{7} - 6 = 20

Required

Justify each step

Step 1:

\frac{4x}{7} - 6 = -20

This is the question in its original form

Step 2:

\frac{4x}{7}  = -14

Here she performed addition property of an equation by adding 6 to both sides of step 1.

This is shown below

\frac{4x}{7} - 6 +6 = -20 + 6

\frac{4x}{7} = -14

Step 3:

4x = -98

Here she performed multiplication property of an equation by multiplying  both sides of step 2 by 7

This is shown below

7 * \frac{4x}{7} = -14 * 7

4x = -98

Step 4:

x = -24.5

Here she also performed multiplication property of an equation by multiplying  both sides of step 3 by ¼

This is shown below

\frac{1}{4} * 4x = -98 * \frac{1}{4}

x = -24.5
