How can you transform the equation 5 + x = 4 into 3 + x = 2?
in 3 + x = 2 , how about adding 2 to both sides ?
I don’t understand
Doesn't x have the same value in each equation?
To transform the equation 5 + x = 4 into 3 + x = 2, you need to perform the same operation on both sides of the equation. Here's how you can do it step by step:
1. Start with the original equation: 5 + x = 4.
2. Subtract 1 from both sides of the equation to make the right side equal to 3 (4 - 1 = 3): (5 + x) - 1 = 4 - 1.
This gives you: 5 + x - 1 = 3.
3. Simplify the left side of the equation: 5 - 1 + x = 3.
This simplifies to: 4 + x = 3.
4. Now, subtract 1 from both sides of the equation to make the right side equal to 2 (3 - 1 = 2): (4 + x) - 1 = 3 - 1.
This gives you: 4 + x - 1 = 2.
5. Simplify the left side of the equation: 4 - 1 + x = 2.
This simplifies to: 3 + x = 2.
So, by subtracting 1 from both sides of the equation twice, you can transform 5 + x = 4 into 3 + x = 2.
