Step-by-step explanation:
3(-x+2x+1)=x-1
3(x+1)=x-1
3x+3=x-1
3x-x=-1-3
2x=-4
x=-2
Answer:
3/2
Step-by-step explanation:
7z+2=8+2z+1z
7z+2=8+3z
7z-3z+2=8
4z+2=8
4z=8-2
4z=6
z=6/4
simplify
z=3/2

Answer:
B, C and E
Step-by-step explanation:
A) 4x + 15 < -21
4x < -36

B) -5/3x + 17/3 < 9
-5x + 17 < 27
-5x < 10
x > -2
=> Yes
C) 1/4x - 16 > -18
1/4x > -2
x > -8
=> Yes
D) -3/2x - 11/4 ≥ 31/4
-3/2x ≥ 42/4
-3/2x ≥ 21/2
x ≤ -7
=> No
E) -8/3x + 5 ≤ 9
-8/3x ≤ 4
x ≥ -4 x 3/8
x ≥ -3/2
=> Yes
4/5, for 4/8=1/2
4/5= 8/10
1/2 (which is 4/8) = 5/10
so 4/5 is greater
hope this helps
