Question

If 4z + 3 = - 7 +; 2z, then z = ?

Answer 1

Answer:

4z+3= -7+2z

4z-2z= -7-3

2z= -10

z = -10/2

z= -5

Hence, z= -5

Answer 2

Question

4z + 3 = -7+2z

Then solution below

Step-by-step explanation:

4z + 3 = -7+2z [subtract both sides -2z]

4z + 3 - 2z = - 7 + 2z - 2z

2z + 3 = -7 [subtract both sides -3]

2z + 3 - 3 = -7 -3

2z = -10 [divide both sides by 2]

2z/2 = -10/2

z = -5 [ your answer]
