Okay, so you what you would is solve one equation for Y=mx+b and then substitute this equation for Y so the answer would be Y=-3/2x + 20
And then you would do 2x-3(-3/2x+20)=-11 and you solve it for x
But to get y you would substitute what you got for x into ether equations.
Answer:
x = (e^4 -2)/3
x≈17.533
Step-by-step explanation:
ln(3x+2)=4
raise each side to e
e^ ln(3x+2) = e^4
3x+2 = e^4
subtract 2 from each side
3x = e^4 -2
divide by 3
x = (e^4 -2)/3
putting this in a calculator
x≈17.533
Cool. I hope she knows how to do it. (ahem)
0.0058 is 0.58% (I think so)
