solve 2x+3y=12 for x
i don't get this one and i am having a hard time solving equations like these. Help? Thank you!
2x+3y = 12
2x = 12-3y
x = (12-3y)/2
keep the term you are solving for on one side:
2x+3y=12
2x = 12 - 3y
divide both sides by 2 to get x alone
2x/2 = (12-3y)/2
x = (12 - 3y)/2 or 6 - 3y/2 or 6 - 1/5y , which ever way you want it.
Thank u!
To solve the equation 2x + 3y = 12 for x, you need to isolate x on one side of the equation.
Here's how you can do it step by step:
Step 1: Start with the given equation: 2x + 3y = 12.
Step 2: To isolate x, we need to get rid of the 3y term. You can do this by subtracting 3y from both sides of the equation. This gives us:
2x + 3y - 3y = 12 - 3y
Simplifying this equation, we have:
2x = 12 - 3y
Step 3: Now, we want to solve for x, so we need to get rid of the coefficient 2 attached to x. We can do this by dividing both sides of the equation by 2. This gives us:
(2x)/2 = (12 - 3y)/2
Simplifying further, we have:
x = (12 - 3y)/2
So the expression for x in terms of y is (12 - 3y)/2.
