Question

Need help with question 7

Answer 1

Answer:

There are two orders in which we can do the steps:

1. GAFDC

2. GABEC

Step-by-step explanation:

$4x-8=5x-2(x+2)$

Step 1 :G Using distributive property to remove parenthesis:

$4x-8=5x+(-2\times x-2\times2)$

$4x-8=5x-2x-4$

Step 2:A Collect like terms:

$4x-8=3x-4$

Step 3: F Add 8 to both sides:

$4x-8+8=3x-4+8$

$4x=3x+4$

Step 4: D Subtract $3x$ from both sides:

$4x-3x=3x+4-3x$

$x=4$

Solution:C

$x=4$

Or

$4x-8=5x-2(x+2)$

Step 1 :G Using distributive property to remove parenthesis:

$4x-8=5x+(-2\times x-2\times2)$

$4x-8=5x-2x-4$

Step 2:A Collect like terms:

$4x-8=3x-4$

Step 4: B Subtract $3x$ from both sides:

$4x-8-3x=3x-4-3x$

$x-8=-4$

Step 3: E Add 8 to both sides:

$x-8+8=-4+8$

$x=4$

Solution:C

$x=4$

There are two orders in which we can do the steps:

1. GAFDC

2. GABEC
