Step 1: Get all the x's on one side: Subtract 2x on both sides:Hi,
Could someone help me with this question:
2x – 1 = 9 – 3x
Thank you in advance!!!
Expand the parentheses:Sorry, there's another one that I'm stuck on too. Really interested to understand the working out on this.
Step 1: Get all the x's on one side: Subtract 2x on both sides:
2x - 1 - 2x = 9 - 3x - 2x
-1 = 9 - 5x
Now do the same with the numbers. Can you finish?

Expand the parentheses:
4(3b - 1) + 6 = 5(2b + 4)
\(\displaystyle 4 \cdot 3b + 4 \cdot (-1) + 6 = 5 \cdot 2b + 5 \cdot 4\)
Now combine terms:
12b - 4 + 6 = 10b + 20
12b + 2 = 10b + 20
Now it's like your first problem. Can you finish?
The second one is okay. Let's take another look at the first one. I left off withThanks Dan - makes this really clear. The first one I get x=4 and the 2nd one I get b=9.
