Answer 2

a) x + 3 = 10 To find the equation with a root of 6, we can substitute 6 for x in each equation and check which one satisfies the equation. Let's check each equation:

a) x + 3 = 10 Substituting x = 6: 6 + 3 = 10 9 = 10

Since 9 is not equal to 10, the equation x + 3 = 10 does not have a root of 6.

b) 9 - x = 5 Substituting x = 6: 9 - 6 = 5 3 = 5

Again, 3 is not equal to 5, so the equation 9 - x = 5 does not have a root of 6.

c) 4x = 24 Substituting x = 6: 4(6) = 24 24 = 24

In this case, both sides of the equation are equal when x = 6. Therefore, the equation 4x = 24 has a root of 6.

d) 30 : x = 4 Substituting x = 6: 30 : 6 = 4 5 = 4

Here, 5 is not equal to 4, so the equation 30 : x = 4 does not have a root of 6.

Therefore, the equation with a root of 6 is c) 4x = 24.
