1) 5x-2x+6-4
5(2)-2(2)+6-4 So plug in 2 for x
Solve on calculator or just distribute it out
10-4+6-4
6+6-4
12-4
8 is your answer
4) 4x-8 is the same as 2(2x-4) if you distribute this out your outcome would be 4x-8
5)
a) 2(3x+4)
6x+8
b)-4(5x+5)
-20x-20
c) -2x+2(4x+1)
Pemdas so
-2x+8x+2
6x+2
d) 5x+2(3x-4)-10
5x+6x-8-10
11x-18
Hope that helps!
