Write algorithm to calculate sum and difference of any two numbers

(step 1 and 2 help clarify the rest of the steps)

first Declare 2 variables →a ,b.

input 2 variables a and b.

print sum=a+b.

print difference = a-b.

print product =a×b.

Step-by-step explanation:

Hope this helps a little :)

BEGIN

DECLARE VARIABLES X, Y

 INPUT VARIABLES X, Y

  READ X, Y

    PRINT SUM = X+Y

    PRINT DIFFERENCE = X-Y

END

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

option: d is correct
