Answer:

a = -12

Step-by-step explanation:

3a – 5(a - 2) = 34

→ Expand out the brackets – 5(a - 2)

– 5(a - 2) = – 5(a + 2) = -5a + 10

→ Substitute that back into the equation

3a - 5a + 10 = 34

→ Simplify the 'a's

-2a + 10 = 34

→ Minus 10 from both sides to isolate -2a

-2a = 24

→ Divide both sides by -2 to isolate a

a = -12

I'm not really sure what to do.
lukranit [14]
I’m not sure if this is right but this looks a bit like chemistry so maybe try to get from minutes to seconds as it becomes an ‘S’ which I’m assuming is seconds? so basically try to do dimensional analysis with it and see if that works. Don’t forget to square it though, that’ll throw you off.
