2x+5 x-5
3
4
Solve the proportion for x
A. -7
B. -4
C-2
D. -1

Answer 1

The proportion can be written as:

(2x + 5)/(3) = (x - 5)/(4)

Multiplying both sides by 12 to eliminate the fractions, we get:

4(2x + 5) = 3(x - 5)

Expanding the brackets, we get:

8x + 20 = 3x - 15

Subtracting 3x and 20 from both sides, we get:

5x = -35

Dividing both sides by 5, we get:

x = -7

Therefore, the solution to the proportion is x = -7.

So, the correct option is A) -7.
