Alex has 3 times as many pets as roman. if they have 24 altogether ,how many do they have ?

Alex has 18 pets, and Roman has 6. I found this out by doing a equation that adds up to 24 with two numbers that multiply ( 6x3 ) up to one of the other numbers so that's how I got 6 and 18.

( or something like that...)

109 is the nearest whole number/final answer! : )

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
