SOLUTION: If x=3 then (4x)^2-3=? If zx+1=7 then x=? If x+18-23 then x=? If 2(x+1)=8 then x=? If 9n<10 then n could be? 5x(14+8) divided by 2=? -x+1<3 then x could equal?

Question 199814: If x=3 then (4x)^2-3=?
If zx+1=7 then x=?
If x+18-23 then x=?
If 2(x+1)=8 then x=?
If 9n<10 then n could be?
5x(14+8) divided by 2=?
-x+1<3 then x could equal?

If x=3 then (4x)^2-3=?
(4*3)^2 - 3 =
12^2 - 3
144 - 3 = 141
:
If zx+1=7 then x=?
zx = 7 - 1
x =
:
If x+18-23 then x=? No way of knowing
:
If 2(x+1)=8 then x=?
2x + 2 = 8
2x = 8 - 2
2x = 6
x =
x = 3
:
If 9n<10 then n could be?
n <
n < 1.11
n could be 1
:
=?; no way of knowing
:
-x+1 < 3 then x could equal?
-x < 3 - 1
-x < 2
x has to be positive, mult by -1, this reverses the inequality sign
x > -2
x could be -1
