Solve for X:
To solve the equation , we'll isolate the variable by performing algebraic operations:
Step 1: Add 8 to both sides of the equation to eliminate the :
This simplifies to:
Step 2: To solve for , we need to change the sign of . Multiply both sides by :
Therefore, the solution to the equation is .
\( 11=a-16 \)
\( a=\text{?} \)
When you see , you want to eliminate the -8. To cancel out -8, you add +8 (because -8 + 8 = 0). Think of it as undoing the -8!
Multiplying by -1 flips the sign of every term. So becomes . It's like taking the opposite of both sides!
Substitute x = -3 back into the original equation: . Since this equals -5, our answer is correct!
The answer x = -3 comes from , not from adding. When we have negative x equals positive 3, then x must be negative to make this true!
Check your work! If you got x = 3, you probably forgot the final step of multiplying by -1. Remember: means x = -3, not x = 3.
