Guys please help me I don’t understand

86

Step-by-step explanation:

due to corresponding angles

(x+3)+(x+5)=180

combine like terms

2x+8=180

Isolate the variable

2x+8=180

    -8   -8

2x=172

/2   /2

86

x=86

its the fourth option

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
