Solution
The correct option is
B
3
The given expression is 3s - 4 = s + 2
Undo the subtraction on the left side using the addition property of equality.
3s - 4 + 4 = s + 2 + 4
⇒ 3s = s + 6
Undo the addition of variable on the right side by using the subtraction property of equality.
3s - s = s + 6 - s
⇒ 2s = 6
Undo the multiplication by using the division property of equality.
2s
÷
2 = 6
÷
2
⇒ s = 3
Hence, the value of s is 3.
