1)
Expanding the expression:
-2(8a + 7b) + 4(a - 2b)= -16a - 14b + 4a - 8b= -12a - 22b
2)
9(2x - 3y) - 8(y - x)= 18x - 27y - 8y + 8x= 26x - 35y
1)
Expanding the expression:
-2(8a + 7b) + 4(a - 2b)
= -16a - 14b + 4a - 8b
= -12a - 22b
2)
Expanding the expression:
9(2x - 3y) - 8(y - x)
= 18x - 27y - 8y + 8x
= 26x - 35y
