Please help me with numbers 1-5 thanks!
Answer :
1) Consider the expression
9x - 2 - 2x + 5 = ( 9 - 2 )x - 2 + 5
= 7x + 3
2) Consider the expression
7x - 4x -x - 12 = (7 - 4 - 1)x - 12
= 2x - 12
3) Consider the expression
- 12 - ( 5y - 10 ) = - 12 - 5y + 10
= - 5y - 2
4) Consider the expression
(8x - 13) - (3x - 1) = (8 - 3)x - 13 + 1
= 5x - 12
5) Consider the expression
- (10v - 6) + 10(2v + 10) = -10v + 6 + 20v + 100
= 10v + 106
6) Consider the expression
8(3x2 - 2) - 6(x2 - 1) = 24x2 - 16 - 6x2 + 6
= (24 - 6)x2 - 16 + 6
= 18x2 - 10
