Question

m:
4x - 7 = 0
+7 +7
3x + 1 = 0
-1 -1

Explanation:

Step1: Solve \(4x - 7 = 0\)

Add 7 to both sides: \(4x - 7 + 7 = 0 + 7\), so \(4x = 7\).
Divide by 4: \(x = \frac{7}{4}\).

Step2: Solve \(3x + 1 = 0\)

Subtract 1 from both sides: \(3x + 1 - 1 = 0 - 1\), so \(3x = -1\).
Divide by 3: \(x = -\frac{1}{3}\).

Answer:

For \(4x - 7 = 0\), \(x = \frac{7}{4}\); for \(3x + 1 = 0\), \(x = -\frac{1}{3}\)
