How do you solve this stupid equation I may or may not have on a test x+(-8)=3x+8

x= -8

Step-by-step explanation:

1.Add 8 to both sides of the equation

2.Simplify

3.Subtract 3 from both sides of the equation

4.Simplify

5.Divide both sides of the equation by the same term

6.Simplify

x=-8

Step-by-step explanation:

Solve the parenthesis first. Keep only the coefficients in the front of the equal sign. Remember that if a negative number passes the equal sign it turns positive and vise versa. Then add the coefficients with the coefficients, and the constants with constants. After that, divide (for example, 4x=8, divide both 4x and 8 by 4, since you only need x.)

Hope it helps you!

answer: x=60

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
