(X+11)=42 Help! how do you do this?

Question

i can't do math other basic to save my life and end of semester is almost over and i need some help.

Answer 1

x + 11 = 42
Cover up the mystery number , x with your hand and then ask what the number under your hand must be to give 42 as an answer.

Answer is x = 31

Answer 2

take it easy and maths will be a piece of cake

(X+11)=42

since there is no number outside the bracket, it means that u times everything inside the bracket by 1 which means that everything stays the same, just remove the brackets!

X + 11 = 42

now .....

ur target is to get X on its own on one side of the equation

there is two ways:

X + 11= 42
-11 -11

X = 31

or

X + 11 = 42
move the 11 to the 42 side of the equation

X = 42 -11

(when u move something from one side to another, the number becomes the opposite of what it was before... ie:2+11 = X ....... 2 = X -11 )



X = 42 -11

42 -11 = 31

so
X =31

check:

31 + 11 = 42!!!!!
yes!
correct!

hope this helped!

Answer 3

x+11 = 42

forget subtracting, u won't do that in a more complicated equation, u are allowed to move the number 11 on the other side of the = by changing the + to a - . So x = 42 - 11 = 31

Answer 4

Here's a step by step procedure:

x + 11 = 42

First thing you got to do is try and isolate the variable to one side of the equation. To do this, you need to do the opposite of everything that is being done to the variable 'x':

x + 11 = 42
...- 11......-11
x = 31

x = 31 is the answer.

Answer 5

x = 31

just subtract 11 from both sides to get:
(x+11)-11 = 42-11
x = 31

Answer 6

subtract 11 from both sides and your left with x=31

(x+11)=42
x+11=42 subtract 11 from both sides
x=31 ANSWER

hope i helped

Answer 7

x+11=42
x+11-11=42-11
x=31

Answer 8

this is a really simple problem.. you should maybe consider getting a tutor, especially if the semester is coming to an end (it'll help for your tests).

anyways:

take out the paranthesis:
x + 11 = 42

isolate the variable (so subtract the 11 from both sides):
x = 31

and there you go : x=31

Answer 9

subtract 11 from the sum(42) to get the variable(x)

Answer 10

subtract 11 from both sides. x= 31
