5-(4y+5)=3+2(4y-6)

how do i combine like terms and what do i do with these()?

On the left side, multiply the terms within the parentheses by -1. The 5s cancel each other out.

-4y = 3 + 2(4y-6)

On the right side, multiply the terms within the parentheses by 2.

-4y = 3 + 4y - 12

Subtract 4y from both sides and combine 3-12.

-8y = -9

You should be able to take it from here.

Psydag is corret but he messed up a little when you multiply right side by 2 you would have gotten

-4y = 3 + 8y - 12 not -4y = 3 + 4y - 12

so you would have subtracted 8y instead of 4y from both side giving you

-12y= -9

and imma leave you to take it from here

To combine like terms, you need to simplify the expression by adding or subtracting terms that have the same variables and exponents. In this equation, you have terms inside parentheses (4y+5) and (4y-6).

To simplify the equation, you can start by following the order of operations, which is often remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication & Division, and Addition & Subtraction).

Let's solve the equation step by step:

1. Distribute the 2 in 2(4y-6). This means you multiply 2 by each term inside the parentheses: 2 * 4y = 8y, and 2 * (-6) = -12.
The equation now looks like this: 5 - (4y + 5) = 3 + 8y - 12.

2. Remove the parentheses by applying the distributive property. Since the parentheses have a minus sign in front, you need to distribute the negative sign to each term inside the parentheses:
The equation becomes: 5 - 4y - 5 = 3 + 8y - 12.

3. Combine like terms on both sides of the equation. On the left side, you have 5 - 5, which equals 0. So the equation becomes: -4y = 3 + 8y - 12.

4. Move all the terms with y to one side of the equation. To do this, you can subtract 8y from both sides: -4y - 8y = 3 - 12.
Simplifying further, you get: -12y = -9.

5. Finally, solve for y by dividing both sides of the equation by -12: y = -9 / -12.
Simplifying the fraction, you get: y = 3/4 or y = 0.75.

In summary, to combine like terms, you need to identify terms with the same variables and exponents, simplify any expressions inside parentheses using the distributive property, and then bring similar terms together by adding or subtracting.
