Which equation has only one solution? A lx-5l=1 B l-6-2xl=8 C l5x+10l=10 D l-6x+3l=0

D:  x = 1/2

Step-by-step explanation:

D is correct.  The solution here is the solution of -6x + 3 = 0, which is x = 1/2.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
