The walls of a bathroom 2,5 m long, 2,05 m wide and 3 m high are to be covered with
tiles, each 15 cm by 15 cm. If a saving of
108 tiles is made on doors and windows,
how many tiles will be needed altogether?
(Note that some tiles will have to be cut.)

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
