Question

What is the value for x when using algebra tiles to solve the equation x+1=-x+(-5)?

Answer 1

x + 1 = -x + (-5)

2x + 1 = -5

2x = -6

x = -3

Answer 2

Answer: The value of x is -3

Step-by-step explanation: We want to solve the equation x+1=-x+(-5)

the first thing we want to do is isolate x, for doing this we may add x in both sides of the eqution, to remove the x therm in the right side:

x+1 +x =-x+(-5) + x

2x + 1 = - 5

now we can subtract 1 in both sides, to remove the 1 in the left side.

2x + 1 - 1 = -5 - 1  

2x = - 6

now we can divide both sides by 2, with the objective of remove the factor 2 in the left side

2x/2 = -6/2

x = -3
