Simplify the expression. 14 - 3z + 8 + Z

A: -2z + 22
B: 2z + 22
C: 4z + 22
D: -4z + 22

A: -2z +22

Step-by-step explanation:

14 - 3z + 8 + z

14 + 8 - 3z + z

   22 - 2z

   -2z + 22

i would have to say it is c.

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
