Using cross multiplication, which of the following is the solution to 2/(x-7) = 3/(x-5)? a.-31 b.11 c.-11 d.31

Hi,

Let's solve the equation step-by-step.

2/(x-7) = 3/(x-5)

Cross Multiply

2/x-7 = 3/x-5

2*(x−5)=3*(x−7)

2x−10=3x−21

Subtract 3x from both sides.

2x−10−3x=3x−21−3x

−x−10=−21

Add 10 to both sides.

−x−10+10=−21+10

−x=−11

Divide both sides by -1.

-x/-1 = -11/-1

x=11

Have a great day!

2(x -5) = 3(x - 7

2x - 10 = 3x - 21

-10 + 21 = 3x - 2x

11 =  x

B is the answer

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
