Ax = 3
Bx = -30
Cx = 30
Dx = -3
Answer & Solution
Correct answer: D. x = -3
1. Distribute one-fourth across the parentheses first, which clears the fraction right away: -5 equals 2x plus 1.
2. Subtract 1 from both sides: -6 equals 2x.
3. Divide both sides by 2 to get x equals -3.
4. Check: one-fourth of (8 times -3, plus 4) equals one-fourth of -20, which equals -5.
