Question

If 125+4x=7y125+4x=7y, what is x in terms of y ?

1) x=4(7y-125)x=4(7y-125)
2) x=4(7y+125)x=4(7y+125)
3) x=(7y-125)÷4x=(7y-125)÷4
4) x=(7y+125)÷4

Answer 1

To find x in terms of y in the equation 125 + 4x = 7y, we need to isolate x on one side of the equation. The correct answer is x = (7y - 125) ÷ 4.

Step-by-step explanation:

To find x in terms of y in the equation 125 + 4x = 7y, we need to isolate x on one side of the equation. We can start by subtracting 125 from both sides:

125 + 4x - 125 = 7y - 125

4x = 7y - 125

Now, to solve for x, we divide both sides by 4:

x = (7y - 125) ÷ 4

Therefore, the correct answer is x = (7y - 125) ÷ 4. This corresponds to option 3.
