The equation x = 6 can be obtained from ………………….. A) 4x

1.	The equation x = 6 can be obtained from ………………….. A) 4x = 6 B) x – 1 = 5 C) x + 6 = 7 D) 5x = 66
Answer» Correct option is B) x – 1 = 5 Correct option is (B) x – 1 = 5 (A) 4x = 6 \(\Rightarrow\) \(x=\frac64=\frac32\) \(\Rightarrow\) \(x=\frac32\) (B) x – 1 = 5 \(\Rightarrow\) x = 5 - (-1) \(\Rightarrow\) x = 5+1 \(\Rightarrow\) x = 6 (C) x + 6 = 7 \(\Rightarrow\) x = 7 - 6 = 1 \(\Rightarrow\) x = 1 (D) 5x = 66 \(\Rightarrow\) x = \(\frac{66}5.\)

The equation x = 6 can be obtained from ………………….. A) 4x = 6 B) x – 1 = 5 C) x + 6 = 7 D) 5x = 66

Answer»

Correct option is B) x – 1 = 5

Correct option is (B) x – 1 = 5

(A) 4x = 6 \(\Rightarrow\) \(x=\frac64=\frac32\) \(\Rightarrow\) \(x=\frac32\)

(B) x – 1 = 5 \(\Rightarrow\) x = 5 - (-1) \(\Rightarrow\) x = 5+1 \(\Rightarrow\) x = 6

(D) 5x = 66 \(\Rightarrow\) x = \(\frac{66}5.\)
