How to solve this equation 6x+3=2x+8
MatroZZZ [7]
You Must Solve For The Value Of X To Make The Equation True. 
So, There Are Two Ways We Could Try This:
Guess And Check
Or
Solve

I Am Going To Show You How To Solve This Because That Is What You Need To Know. So, We First Need To Look At It.

6x + 3 = 2x + 8

So, we need to subtract 3 from the right side's 8 to begin.
The equation becomes:

6x = 2x + 5

Now, We Need To Simplify The 2x. Subtract 2x from 6x. 
The Equation Becomes:

4x = 5

Now, Divide.

4x/4 = 1x = X

So,

X = 5/4

5/4 = 1 and 1/4

So

X = 1 ¼

Write an equation of the line with the given information. m. 4. A(-1.-5)
11Alexandr11 [23.1K]

Answer:

An equation of the line with the given information with

m = 4 and point A(-1, -5) is:

  • y=4x-1

Step-by-step explanation:

As the equation of a line in point-slope form is given by:

y-y_1=m\left(y-x_1\right)

where m is the slope.

Given:

  • the slope m = 4
  • the point A(-1, -5)

Substituting the values in the equation of a line in point-slope form

y-y_1=m\left(x-x_1\right)

y\:-\:\left(-5\right)\:=\:4\:\left(x\:-\:\left(-1\right)\right)

y+5=4\left(x+1\right)

subtract 5 from both the sides

y+5-5=4\left(x+1\right)-5

y=4x-1

Therefore, an equation of the line with the given information

with m = 4 and point A(-1, -5) is:

  • y=4x-1
