Which equation has an infinite number of solutions? A. 3x - 2(x + 10) = x - 20
B. 5x + 2(x - 3) = 5x + 2( 3 - x)
C. x/2 + 1 = 3x/10 + 3
D. 7/2 x + x = 7/4

3x-2 (x+10)=x-20

Step-by-step explanation:

don't report but were is the digram

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
