Answer:
To solve linear equations we will make heavy use of the following facts. If a=b then a+c=b+c a + c = b + c for any c .
...
Process for Solving Linear Equations
1- If the equation contains any fractions use the least common denominator to clear the fractions. ...
2- Simplify both sides of the equation.

Answer:
y= ¼x
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.
Slope
Substitute the value of the slope into the equation:
y= ¼x +c
To find the value of c, substitute a pair of coordinates.
When x= 12, y= 3,
3= 3 +c
c= 3 -3
c= 0
Thus, the equation of the line is y= ¼x.
In order to solve for x in the equation <span>7x + 15 = 38, you must first subtract 15 from both sides.
</span><span>7x + 15 = 38
</span><span>7x + 15 - 15 = 38 - 15
7x = 23
Then you must divide so there is only 1x = a number. This can be done by dividing both sides by 7.
7x = 23
7x / 7 = 23 / 7
x ≈ </span>3.286
So the solution for x in the equation 7x + 15 = 38 is x ≈ 3.286.
Hope this helps!
Answer:
5x + 6
Step-by-step explanation:
4x - 3 + 2x + 1 - x + 8
= 4x + 2x - x -3 + 1 +8
= 5x + 6
