Solve using the addition principle.
x + 1 = 7
see other post.
x+1=7. Add -1 to both sides then u should end up with x=6. That's technically the answer but there's more to do. Then divide each side by x (1) so that's the answer. X=6
To solve the equation x + 1 = 7 using the addition principle, we need to isolate the variable x. The addition principle states that if we add the same number to both sides of an equation, the equality will still hold.
Step 1: Subtract 1 from both sides of the equation:
x + 1 - 1 = 7 - 1
x = 6
Therefore, the solution to the equation x + 1 = 7 is x = 6.
