Answer:
Bryce is wrong in step 1 because he did not distribute 3 over 5/3
Explanation
Given the steps taken by bryce as shown, we are to find where he made an error
Given the expression;
Step 1:Expand the bracket using the distributive law;
8/3 = 3c + 3(5/3)
<em>Simplify</em>
8/3 = 3c + 15/3
Step 2: Subtract 15/3 from both sides
8/3 - 15/3 = 3c+15/3-15/3
(8-15)/3 = 3c
-7/3 = 3c
Step 3: Multiply both sides by 1/3
-7/3 * 1/3 = 3c * 1/3
-7/9 = c
Swap
c = -7/9
From the calculation, we can see that Bryce is wrong in step 1 because he did not distribute 3 over 5/3 thereby making his solution incorrect
Answer:
x = -
Step-by-step explanation:
Given
- 2(4x + 3) = 3(x + 1) ← distribute parenthesis on both sides
- 8x - 6 = 3x + 3 ( subtract 3x from both sides )
- 11x - 6 = 3 ( add 6 to both sides )
- 11x = 9 ( divide both sides by - 11 )
x = -
