Question

8.) 8(7x - 3) - 8(x + 8)
9.) 6(4x + 11) + 2(x + 8)
10.) 8(x + 1) + 5(4x - 7)

Explanation:

Step1: Expand each term (Q8)

$8(7x - 3) - 8(x + 8) = 56x - 24 - 8x - 64$

Step2: Combine like terms (Q8)

$56x - 8x - 24 - 64 = 48x - 88$

Step3: Expand each term (Q9)

$6(4x + 11) + 2(x + 8) = 24x + 66 + 2x + 16$

Step4: Combine like terms (Q9)

$24x + 2x + 66 + 16 = 26x + 82$

Step5: Expand each term (Q10)

$8(x + 1) + 5(4x - 7) = 8x + 8 + 20x - 35$

Step6: Combine like terms (Q10)

$8x + 20x + 8 - 35 = 28x - 27$

Answer:

1. $48x - 88$
2. $26x + 82$
3. $28x - 27$
