Answer

7 $is a solution to the equation$ 3x + 4 = 20$:

Here's how to check if $x=7$ is a solution to the equation $3x + 4 = 20$ :

Step 1: Write the given equation. $3x + 4 = 20$

Step 2: Substitute $x=7$ into the equation. $3(7) + 4 = 20$

Step 3: Perform the multiplication. $21 + 4 = 20$

Step 4: Perform the addition. $25 = 20$

Step 5: Compare both sides of the equation. Since $25 \neq 20$ , the value $x=7$ is not a solution to the equation $3x + 4 = 20$ .

The correct answer is: ❌ Incorrect. $x=7$ is not a solution to the equation $3x + 4 = 20$ .
