Susan's math teacher assigned x homework problems on monday. on tuesday, she assigned 13 more problems. over the two days, a total of 21 homework problems were assigned. which equation could be used to find x, the number of problems assigned on monday?
a. x - 13 = 21
b. x + 13 = 21
c.21 + x = 13
d.13x = 21

i can answer this question sweetie!

step-by-step explanation:

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
