Write this as a problem.

Add 5 to the sum of x and 21 times 7 and the result is 21.

x+(21*7)+5=21

Check my thinking. Check my work.

Thank you

Let's write this problem as a mathematical equation:

x + (21 * 7) + 5 = 21

To solve this equation, we can start by simplifying the expression 21 * 7:

x + 147 + 5 = 21

Now, we can combine like terms to simplify further:

x + 152 = 21

Next, we can isolate the variable x by subtracting 152 from both sides of the equation:

x + 152 - 152 = 21 - 152

This simplifies to:

x = -131

Therefore, the value of x that satisfies the equation is -131.
