I am joyous to assist you anytime.
First you divide 380 by 100 to get what 1% is, (3.8) and then you multiply by 18 to give you 18%. The answer is 68.4, so add that to 380 and you'll have the final answer of 448.4.

Well, if
{bx - 6y = 18 and {2x - 3y = 9, you might want to try elimination
Multiply second equation by -2: bx - 6y = 18 and -2(2x - 3y = 9)
Simplified: bx - 6y = 18 and -4x + 6y = -18
Now if you add them you get: -4x + bx = 0
Then simplified: bx = 4x
divide by x: b = 4
Your final solution is b = 4.
Hope that helps!
