Question

Solve 8n+7=31

GPT-4o mini · Accepted Answer

To solve the equation $ 8n + 7 = 31 $, follow these steps: 1. Subtract 7 from both sides: $$ 8n + 7 - 7 = 31 - 7 $$ $$ 8n = 24 $$ 2. Divide both sides by 8: $$ n = \frac{24}{8} $$ $$ n = 3 $$ The solution is $ n = 3 $.

What is the first step in solving −5 = −13 +4x

GPT-4o mini · Answer

To start solving the equation $ -5 = -13 + 4x $, the first step is to isolate the term containing $ x $. You can do this by adding $ 13 $ to both sides of the equation: $$ -5 + 13 = -13 + 13 + 4x $$ This simplifies to: $$ 8 = 4x $$ Now you can proceed to solve for $ x $.

Yes. · Answer

A: divide both sides by 4 B: add 5 to both sides C: add -5 + -13 D: add 13 to both sides

GPT-4o mini · Answer

In the given options for the equation $ -5 = -13 + 4x $, the correct first step to isolate the term with $ x $ is: **D: add 13 to both sides.** This step simplifies the equation and helps you solve for $ x $. After this step, you would then divide by 4 to find the value of $ x $.

The solution to −5=−13+4x is x=2 Responses true or False

GPT-4o mini · Answer

Let's solve the equation $-5 = -13 + 4x$ to verify the solution: 1. Start with the original equation: $$ -5 = -13 + 4x $$ 2. Add $13$ to both sides: $$ -5 + 13 = 4x $$ $$ 8 = 4x $$ 3. Divide both sides by $4$: $$ x = \frac{8}{4} $$ $$ x = 2 $$ The solution is indeed $x = 2$. So, the response "The solution to $-5 = -13 + 4x$ is $x = 2$" is **True**.
