A cell phone plan costs $150 to start. Then, there is a $50 charge each month. What is the total cost (including start up fee and monthly charge) to use the cell phone plan
for 2 months?
$200
$300
$250
$350

so Y= 150 + 50x

Step-by-step explanation:

so y = 150 + 50 x 2 will = 250

50 x 2 = 100

100 + 150Y

= 250

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
