To determine which equation is true when the value of w is -18, we can substitute -18 for w and see which equation holds true.
Let's substitute -18 for w in each equation and simplify:
1) 15 - (1/2)w = 21
15 - (1/2)(-18) = 15 + 9 = 24 ≠ 21
2) 3w + 4 = -45
3(-18) + 4 = -54 + 4 = -50 ≠ -45
3) 24 - 3w = 78
24 - 3(-18) = 24 + 54 = 78 ✔️
4) 2w + 10 = 26
2(-18) + 10 = -36 + 10 = -26 ≠ 26
Therefore, the equation that is true when the value of w is -18 is 24 - 3w = 78.
