Red and blue cubes
In a bag, there are red and blue cubes in the ratio 4:7

red: blue
4:7

I add 10 more red cubes to the bag.

Now there are red and blue cubes in the ratio 6:7

red: blue
6:7

How many blue cubes are in the bag?

answer:   rlly

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
