23. 7(3x) =
Simplify the expression

21x im pretty sure

Step-by-step explanation:

21x

Step-by-step explanation:

7(3x) is basically 7 times 3x. We can multiply the constant with the coefficient and get 21. Since x is also being multiplied, we can do 21 * x. We can simplify this to be 21x.

I hope this helped and please mark me as brainliest!

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
