12 - 2x = 50
Solve by describing your steps

Step-by-step explanation:

1 move 12 to other side

2 divide both sides by -2

3 its -19

X= -19

Step-by-step explanation:

12 - 2x = 50 is the same thing as -2x + 12 = 50. So from here we can use inverse operations to find the value of x. That would mean -2x= 38.

so that would mean x= -19

a) false; the points do not have to be in a straight line.

step-by-step explanation:

the points could be in the shape of a triangle

b is incorrect

c is incorrect because it is saying the immediately don't form one when they are capable of doing so

d is incorrect

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
