3m+5/m-2=-5/7
please solve this question i will mark as brainleast​

Answer 1

Step-by-step explanation:

1 Multiply both sides by 7m7m.

21{m}^{2}+35-14m=-5m21m

2

+35−14m=−5m

2 Move all terms to one side.

21{m}^{2}+35-14m+5m=021m

2

+35−14m+5m=0

3 Simplify 21{m}^{2}+35-14m+5m21m

2

+35−14m+5m to 21{m}^{2}+35-9m21m

2

+35−9m.

21{m}^{2}+35-9m=021m

2

+35−9m=0

4 Use the Quadratic Formula.

m=\frac{9+\sqrt{2859}\imath }{42},\frac{9-\sqrt{2859}\imath }{42}m=

Answer 2

Answer:

196

Step-by-step explanation:

3m+5/m-2=-5/7

3m^2/m+5/m=-5/7

3m^2+5/m=-5/7

7(3m^2+5)=5/7×m

21m^2+35=5m/7

m^2-m=(21+35)7/5

m=147+245/5

m=147+49

therefore,m=196
