Question

2x-z + 1.5y + 5 (b) 2(x + z) – ( 2 + y) -1.5y + 2

Answer 1

Steps

2x−z+1.5y+5(b)· 2(x+z)−(2+y)−1.5y+2

Remove parentheses: (a)=a

=2x−z+1.5y+5b· 2(x+z)−(2+y)−1.5y+2

Multiply the numbers: 5· 2=10

=2x−z+1.5y+10b(x+z)−(y+2)−1.5y+2

Expand 10b(x+z): 10bx+10bz

=2x−z+1.5y+10bx+10bz−(2+y)−1.5y

−(2+y): −2−y

=2x−z+1.5y+10bx+10bz−2−y−1.5y+2

Simplify 2x−z+1.5y+10bx+10bz−2−y−1.5y+2: 2x+10bx+10bz−z−y

=2x+10bx+10bz−z−y
