Answer 1

Answer:

x=1

Step-by-step explanation:

To solve, we need to get x by itself. To do this, preform the opposite of what is being done to the equation, and everything that is done to one side, must be done to the other.

5(2x-8)+15= -15

First, subtract 15 from both sides, since 15 is being added

5(2x-8)+15-15=-15-15

5(2x-8)=-30

Next, divide both sides by 5 since 5 is being multiplied

5(2x-8)/5= -30/5

2x-8= -6

Add 8 to both sides, since 8 is being subtracted

2x-8+8= -6+8

2x= 2

Divide both sides by 2, since 2 is being multiplied

2x/2= 2/2

x=1

Answer 2

Answer:

x=1

Step-by-step explanation:

5(2x-8)+15=-15

first do what is in parentheses, multiply the 5 with 2x and -8.

10x-40+15=-15

add 15 to -40

10x-25=-15

add 25 to both sides

10x=10

divide 10 on both sides

x=1
