Simplify the expression by adding (or subtracting) like terms: 5x + 5 + 2x + 5x − 5y − 2y − 2x

Step-by-step explanation:

Step 1: Identify like terms.

Step 2: Rewrite using properties of operations when necessary.

Step 3: Simplify.

Step 4: Check by substitution.

Therefore, the correct answer is 10x-7y+5

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
