Solve using elimination

12s+7l=332

9s+14l=424

Will mark as brainlist

s = 16

l = 20.

Step-by-step explanation:

12s + 7l =  332  

9s + 14l =  424

Multiply first equation by -2:

-24s - 14i = -664      Now add this to second equation:

-15s = -240

s = 16

Now substitute s = 16 in equation 2:

9(16) + 14i = 424

14i = 424 - 144 = 280

l = 20.

answer is b

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
