How do I get better at solving equations with variables on both sides?

Question

A simple method for solving equations with variables on both sides — perfect for Algebra 1 students who want structure, confidence, and better grades.

Answer 1

Great Question!

Here's the play by play:

1. Bring all variable terms on one side and all constant terms on the other.
2. Combine all the variable terms (like terms). Combine all all constant terms on the other side.
3. Solve for x by dividing by the coefficient on both sides.

Answer 2

Great Question!

When we see an equation with variables on both sides, like x + 3 = 2x + 1, it means we’re trying to figure out what number x has to be to make both sides equal. You can think of it like a balance scale—whatever you do to one side, you have to do the same to the other to keep it fair. The goal is to get x all by itself on one side of the equation. To do that, we can move the x terms and number terms around, just like solving a puzzle. For example, we can take away x from both sides to get 3 = x + 1, and then subtract 1 from both sides to find x = 2. It's just like figuring out how many mystery items are in a bag when we know the total is the same on both sides. Step by step, we simplify until we find out what x equals!

Answer 3

3x+5=2x-7 first we do variable arrange on left side change it sin - from right to left and non variable in right side also change it sin -from left to right such as 3x-2x=-7-5 now they can solved like x=-12

Answer 4

Great question — equations with variables on both sides can feel tricky at first, but they follow a consistent playbook.

Here’s the step-by-step strategy:

1. Move all variable terms to one side: Use addition or subtraction to combine like terms (e.g., move all x’s to the left).
2. Move constants to the other side: Isolate the variable by shifting the numbers without x.
3. Simplify: Combine and divide to solve for the variable.
4. Check your solution: Plug your answer back into the original equation to confirm.

Example:

Solve 3x + 5 = 2x – 7

→ Subtract 2x from both sides: x + 5 = –7

→ Subtract 5: x = –12

→ Plug back in to check.

Confidence comes with reps — and structure. Once this process becomes second nature, these problems get a lot easier.
