White shapes and black shapes are used in a game.
some of the shapes are circles.
all of the other shapes are squares
the ratio of the number of white shapes to the black shapes is 3: 7
the ratio of the number of white circles to the number of white squeres is 4: 5 the ratio of the number of black circles to the number of black squesres is 2: 5 work out what fraction of all the shapes are circles

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
