Question

if 3(4m+5)-4(3-2m)=13then m=?​

Answer 1

Answer:

1/2

Step-by-step explanation:

3(4m+5)-4(3-2m)=13

12m + 15 -12 +8m =13

20m +3 =13

20m =13-3

20m =10

m = 10 /20

m = 1/2

Answer 2

Step-by-step explanation:

3 ( 4m + 5 ) - 4 ( 3 - 2m) = 13

12m + 15 - 12 + 8m = 13

20m + 3 = 13

20m = 13 - 3

20m = 10

$m \: = \frac{10}{20 } \\ m = \frac{1}{2}$
