Which could be a step used when solving the equation 5x+10=7.5x? distribute 5

distribute 10

add 10 to both sides

subtract 5x from both sides

subtract 5x from both sides

Step-by-step explanation:

7.5-5=2.5

2.5=10

10÷2.5=4

x=4

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

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
