2x+7=79
i think it is 43
No.
You need to subtract 7 from both sides of the equation.
Please try again.
32 1/2
You're closer, but still wrong.
Check your division.
2x+7=79
2 x + 7 - 7 = 79 - 7
2 x + 0 = 72
2 x/2 = 72/2
x = 72/2
72 inches is six feet so half of that is three feet which is 36 inches :)
To solve the equation 2x + 7 = 79, you need to isolate the variable x.
Step 1: Start by subtracting 7 from both sides of the equation:
2x + 7 - 7 = 79 - 7
This simplifies to:
2x = 72
Step 2: Next, divide both sides of the equation by 2 to solve for x:
2x/2 = 72/2
This simplifies to:
x = 36
Therefore, the value of x that satisfies the equation 2x + 7 = 79 is x = 36, not 43 as you initially thought.
