What is the value of x?

6x=72

show how you got the answer

x=12

Step-by-step explanation:

6x=72

Divide both sides by 6

6x/6=72/6

x=12

It can also be solved this way

6x=72

Multiply both sides by 1/6

6x(1/6)=72(1/6)

6x/6=72/6

x=72/6

x=12

To check if correct, x will be substituted for 12 in the equation, and both sides of the equation must be equal

6x=72

6(12)=72

6X12=72

72=72

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
