3)21 = m + 6 4) 4 = x − 9 4) 4) 4 = x − 9

5) b − 17 = −16 6) −4 = x − 17

Plz help

Explanation:

Switch sides:

m + 6 = 21

Subtract 6 from both sides:

m + 6 - 6 = 21 - 6

Simplify:

Switch sides

x - 9 = 4

Add 9 to each side:

x - 9 + 9 = 4 + 9

Simplify:

Add 17 to each side:

b - 17 + 17 = -16 + 17

Simplify:

Switch sides:

x - 17 = -4

Add 17 to each side:

x - 17 + 17 = -4 + 17

Simplify:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
