Someone me solve #19 with steps on how to solve?

a.9

b. ay=9

xy= 18

Step-by-step explanation:

a. xa=ay (since a is a midpoint that means xa and ay are the same amount).

3x=5x-6

subtract 5x from both sides

-2x=-6

inverse operations, so divide both sides by -2. (a negative divided by a negative is a positive)

x=3

so xa=3x. fill in x

3*3 is 9

b. fill in the x

5*3-6

5 times 3 is 15.

15-6=9

(also xa is 9 and they are congruent so both are 9)

ay= 9

add both sides to find xy

9+9=18

xy=18

infinitely many solutions

step-by-step explanation:

we have been given the equation;

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

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
