Q: Solve |2x - 5| = 4.
A: |2x - 5| = 4 2x - 5 = -4 or 2x - 5 = 4 2x - 5 = -4; 2x = -4 + 5; 2x = 1; x = 1/2; 2x - 5 = 4; 2x = 4 + 5; 2x = 9; x = 9/2; x = 1/2 or x = 9/2

|2x - 5| = 4

2x - 5 = -4 or 2x - 5 = 4

2x - 5 = -4;
2x = -4 + 5;
2x = 1;
x = 1/2;

2x - 5 = 4;
2x = 4 + 5;
2x = 9;
x = 9/2;

x = 1/2 or x = 9/2

Solve for x. 3x /6+ 1 = 7
Question
Updated 8/22/2014 2:27:10 AM
3x /6+ 1 = 7
1/2x +1 = 7
1/2x = 7 - 1
1/2x = 6
1/2x/1/2 = 6/1/2
x = 12
If f(x) = 2x squared - x, find f(-3).
Weegy: f(x) = 2x^2 - x, find f(-3). f(-3) = 2(-3)^2 + 3 f(-3) = 2(9) + 3 f(-3) = 18 + 3 f(-3) = 21 (More)
