Algebra Find the value of each variable.

Please please help me

Step-by-step explanation:

4. x=50 because 28+17=45, 180-85-45

y=130 becaue 180-50

z=5 because 180-130-45

5. z=59 because 40+24 =64, 180-64-57

y=121 becayse 180-59

x=5 because 180-121-64

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
