Select all equations that have the solution x = 7.

1st,2nd, and 4th

Step-by-step explanation:

1)

2x + 14 = 28➡ x = 7

2)

60 = 4x + 32 ➡ x = 7

3)

2x - 6 -12 = -2x - 20 ➡ 4x = -2x = -1/2

4)

3x - 15 = 1 + 5x - 30 ➡14 = 2x ➡ x = 7

Hey!

Solve 2(x + 7) = 28 with x = 7.

2(7 + 7) = 28

2(14) = 28

28 = 28

TRUE

Solve 60 = 4(x + 8) with x = 7.

60 = 4(7 + 8)

60 = 4(15)

60 = 60

TRUE

Solve 6(2x - 1) - 12 = -2(x + 10) with x = 7.

6(2(7) - 1) - 12 = -2(7 + 10)

6(14 - 1) - 12 = -2(17)

6(13) - 12 = -2(17)

78 - 12 = -34

66 ≠ -34

FALSE

Solve 3(x - 5) = 1 + 5(x - 6) with x = 7.

3(7 - 5) = 1 + 5(7 - 6)

3(2) = 1 + 5(1)

6 = 1 + 5

6 = 6

TRUE

Hence, the correct answers are A, B, and D!
