Me asap! will award brainliest! it's about simultaneous equations. tysm ; )
solve:
y=3x–3
4x+y=11

Plug in your Y value into the bottom equation like so:

4x + 3x-3=11, combine like terms

7x-3=11 solve for x

7x= 14

x=2

Plug in x value into first equation

y = 3(2) -3

y= 6-3, y = 3

(2,3)

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

i think that you should ask google for the answer to that problem because if we don't know it google does
