Question

solve:
13 (z+4) -3 (z-9)=5 (z+4)
pls explain​

Answer 1

$13(z + 4) - 3(z - 9) = 5(z + 4)$

$13z + 52 - 3z + 27 = 5z + 20$

$10z + 79 = 5z + 20$

$10z - 5z = 20 - 79$

$5z = - 59$

$z = \frac{ - 59}{5}$

Answer 2

Step-by-step explanation:

13(z+4)-3(z-9)=5(z+4)

13z+52-3z-27=5z+20

13-3z+52-27=5z+20

10z+25=5z+20

10z-5z=20-25

5z=-5

z=-5/5

therefore z=-1
