mong a group of 5 participants who were all exposed to asbestos without proper personal protective equipment when working in retrofitting old buildings.

Find the value of x when 6-4x = 6x-8x-2.
mestny [16]

Answer:

4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6−4x=6x−8x−2

6+−4x=6x+−8x+−2

−4x+6=(6x+−8x)+(−2)(Combine Like Terms)

−4x+6=−2x+−2

−4x+6=−2x−2

Step 2: Add 2x to both sides.

−4x+6+2x=−2x−2+2x

−2x+6=−2

Step 3: Subtract 6 from both sides.

−2x+6−6=−2−6

−2x=−8

Step 4: Divide both sides by -2.

−2x−2=−8−2

x=4

I need help with math -4+a=15
MrMuchimi

Note the equal sign. What you do to one side, you do to the other. Isolate the a.

Add 4 to both sides

a- 4 (+4) = 15 (+4)

a = 15 + 4

a = 19

19 is your answer for a

hope this helps
