Recall the compound interest formula

Where r = 0.04, n = 12 since compounded monthly, t = 30, and p, initial value, is 24000.
Plug them in, 79523.95 seems to be the solution.
X = 6iy-4y+83-66i/13
y= 14+9i/2-x-3xi/2
B 24a-22=-4(1-6a) has no solution
If there’s a picture I’m not able to see it
EXPLANATION:
Let the no. be x.
4x-12= -11
4x= -11+12
x=1/4
x=0.25
ANSWER:
x=0.25
Hope it helps u! :)
