How do you work out the equation 1-x=9.
1 answer:
Answer:
x=8
Step-by-step explanation:
x + 1 = 9
Simplifying
x + 1 = 9
Reorder the terms:
1 + x = 9
Solving
1 + x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1' to each side of the equation.
1 + -1 + x = 9 + -1
Combine like terms: 1 + -1 = 0
0 + x = 9 + -1
x = 9 + -1
Combine like terms: 9 + -1 = 8
x = 8
Simplifying
x = 8
