64-7C
-76-7C**
4-13C
-16-13C

2) 5x+6(x-2) -8(x-3)

19x+12
3x-36
3x+12

For question 2

Answer 1

Oops I meant to say for question 2 I got 9x-11x, so I know something went wrong there.

Answer 2

Question 2 is 3x+12

Answer 3

1. is right and 2. Simplifying
5x + 6(x + -2) + -8(x + -3)

Reorder the terms:
5x + 6(-2 + x) + -8(x + -3)
5x + (-2 * 6 + x * 6) + -8(x + -3)
5x + (-12 + 6x) + -8(x + -3)

Reorder the terms:
5x + -12 + 6x + -8(-3 + x)
5x + -12 + 6x + (-3 * -8 + x * -8)
5x + -12 + 6x + (24 + -8x)

Reorder the terms:
-12 + 24 + 5x + 6x + -8x

Combine like terms: -12 + 24 = 12
12 + 5x + 6x + -8x

Combine like terms: 5x + 6x = 11x
12 + 11x + -8x

Combine like terms: 11x + -8x = 3x
12 + 3x
