Question

9z-13=11z+27 solve and check ..​

Answer 1

Answer:

9 z -13 = 11 z + 27

9 z - 11 z = 27 + 13

- 2 z = 40

z = -20

for checking put value of z = -20 in both sides....

9(-20) - 13 = 11(-20) + 27

-180 - 13 = -220 + 27

- 193 = - 193

L.H.S = R.H.S

therefore, the value of z= -20 is correct.

Answer 2

Answer:

z=-20

Step-by-step explanation:

9z-13=11z+27

-27-13=11z-9z

-40=2z

-40\2=z

z=-20

check::

9z-13=11z+27

take z=-20

9(-20)-13=11(-20)+27

-180-13=-220+27

-193=-193

so L.HS.=R.H.S

plzzs mark as a briliant answer .
