Solve for x: 5x - 3 = 2x + 12
Answer: x = 5
5x - 2x = 12 + 3 → 3x = 15 → x = 5.
Solve: 2(x + 4) = 3(x - 1)
Answer: x = 11
2x + 8 = 3x - 3 → 8 + 3 = 3x - 2x → x = 11.
Solve the inequality: 4x + 7 > 19
Answer: x > 3
4x > 12 → x > 3.
Solve for y: y/3 + 5 = 9
Answer: y = 12
y/3 = 4 → y = 12.
Solve: 3x² = 75
Answer: x = ±5
x² = 25 → x = ±5.
Solve: (x - 2)/4 = (x + 1)/3
Answer: x = -10
Cross multiply: 3(x-2) = 4(x+1) → 3x - 6 = 4x + 4 → -x = 10 → x = -10.
