Question

Solve the equation: 42dx - 7dx = 70f.

(A) d = 2f
(B) d = 10f
(C) d = 5f
(D) d = 7f

Answer 1

(A) d = 2f. To solve the equation, combine like terms and isolate dx by dividing both sides by 35 to get dx = 2f.

Step-by-step explanation:

To solve the equation, we need to combine like terms on the left side:

42dx - 7dx = 70f

35dx = 70f

Next, we divide both sides of the equation by 35 to isolate dx:

dx = 2f

Therefore, the solution is (A) d = 2f.
