7(w+5)-15+4(4w+x)+12x

answer:

23w+16x+20

Step-by-step explanation:

Let's simplify step-by-step.

7(w+5)−15+4(4w+x)+12x

Distribute:

=(7)(w)+(7)(5)+−15+(4)(4w)+(4)(x)+12x

=7w+35+−15+16w+4x+12x

Combine Like Terms:

=7w+35+−15+16w+4x+12x

=(7w+16w)+(4x+12x)+(35+−15)

=23w+16x+20

answer:

=23w+16x+20

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
