°° Let's see -

First, you want to rewrite the equation:

x + 67 = 83

Let's do the 1 lonely step -

Subtract 67 from both sides of the = sign.

x + 67 - 67 = 83 - 67

Now, as you can see, our unknown 'x' equals 16

x = 16

______________________________________________________

Want to check your answer?

Just substitute the 16 for the x and then solve.

16 + 67 = 83

We were correct!

↑ ↑ ↑ Hope this helps! :D

(Note: When solving for variables like this, just use my method as a guide to help you get the answer to other problems! Example below)

Sample Example:

x + 48 = 92

Do our 1 lonely step: Subtract 48 from both sides.

x + 48 - 48 = 92 - 48.

x = 44

Check:

Switch the 'x' with the 44!

44 + 48 = 92!

TADA! We're done! Hope you enjoyed reading this!

Solve:-

x + 67 = 83
Inverse operation.
83 - 67 = x
83 - 67 = 16
x = 16

Check:-
x + 67 = 83
x = 16
16 + 67 = ?
16 + 67 = 83
Correct!

x = 16

Answer:

Step-by-step explanation:

First, write an equation to represent the situation.

34 = 2a + 12

This equation works because your combined age is half of 68, so 34. If your age is a, then yours sister's age is a + 12. if you add your age to your sister's, you get 2a + 12.

Now just solve for a.

34 = 2a + 12

First, subtract 12 from both sides.

22 = 2a

Then divide both sides by 2.

11 = a

So you are 11 years old. If you need to check your work, your age (11) plus your sister's age (11 + 12, which is 23) is 34, which is half of your grandfather's age.

What is the equation of the graphed line in point-slope form?

Flura [38]

We first need to find the gradient of the line
$\frac{y_{2}- y_{1} } {x_{2}-x_{1} } = \frac{-3-1}{-3-3}= \frac{-4}{-6}= \frac{2}{3}$

From the graph, we see the graph intercepts y-axis at -1

Hence, the equation of the line is $y= \frac{2}{3}x-1$
