Question

Do y’all know the answer go r 7-3r=r-4(2+r)

Answer 1

isolate the variable r by moving 7 to the other side of the equation: the solution to the equation
`\(7 - 3r = r - 4(2 + r)\) is \(r = -15\).`

Explanation:

To solve the equation 7 - 3r = r - 4(2 + r), start by distributing the -4 across the terms inside the parentheses, resulting in 7 - 3r = r - 8 - 4r. Combine like terms by adding 4r to both sides of the equation, yielding 7 + r = -8. Then, subtract 7 from both sides to isolate the variable, giving r = -1 as the final solution.

Certainly! Let's solve the equation step by step:

Given equation:
`\(7 - 3r = r - 4(2 + r)\)`

First, distribute the -4 across the terms inside the parentheses:

`\(7 - 3r = r - 8 - 4r\)`

Now, let's simplify the equation by combining like terms:

Combine the r terms by adding 4r to both sides of the equation:

`\(7 - 3r + 4r = r - 8 - 4r + 4r\)`

`\(7 + r = -8\)`

Now isolate the variable r by moving 7 to the other side of the equation:

`\(r = -8 - 7\)`

`\(r = -15\)`

Therefore, the solution to the equation
`\(7 - 3r = r - 4(2 + r)\) is \(r = -15\).`
