Solve the equation 7x=15+6 using substitution.(1 point)
x=

Answer 1

To solve the equation 7x = 15 + 6 using substitution, we can substitute the value of 15 + 6 into the equation:

7x = 15 + 6

Simplifying, we get:

7x = 21

To solve for x, we can divide both sides of the equation by 7:

x = 21/7

Simplifying further, we get:

x = 3

Answer 2

Use substitution to determine which number(s) from the set {9, 12, 14} make the equation 6x=72 true.(1 point)
x= [__]

Answer 3

To use substitution to determine which number(s) from the set {9, 12, 14} make the equation 6x = 72 true, we can substitute each number into the equation:

For x = 9:

6(9) = 54

For x = 12:

6(12) = 72

For x = 14:

6(14) = 84

Out of the given set {9, 12, 14}, only x = 12 makes the equation 6x = 72 true.

Answer 4

Use substitution to determine which number(s) from the set {4, 5, 6} make the equation 7x−6=29 true.(1 point)
x=

Answer 5

To use substitution to determine which number(s) from the set {4, 5, 6} make the equation 7x - 6 = 29 true, we can substitute each number into the equation:

For x = 4:

7(4) - 6 = 22 ≠ 29

For x = 5:

7(5) - 6 = 35 - 6 = 29

For x = 6:

7(6) - 6 = 42 - 6 = 36 ≠ 29

Out of the given set {4, 5, 6}, only x = 5 makes the equation 7x - 6 = 29 true.
