To solve for x, we will first simplify the equation:
2(x - 3) + 21 = -3
Expanding the left side:
2x - 6 + 21 = -3
Combine like terms:
2x + 15 = -3
Next, we will isolate the variable x by subtracting 15 from both sides:
2x = -3 - 15
2x = -18
Finally, we divide both sides by 2 to solve for x:
x = -18 / 2
x = -9
Therefore, the value of x that makes the equation true is x = -9.
