Answer:
b. x = 11/8, x = 59/72.
Step-by-step explanation:
4|8x - 6| = 5|-8x + 7|
square both sides:
16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)
1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0
576x^2 - 1264x + 649 = 0
x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)
x = 11/8, x = 59/72.

Answer:
shirt= $8
cap=$3
Step-by-step explanation:
rearrange one of the equations
y=11-x
then plug into the other equation
2x+3(11-x)=25
solve
2x+33-3x=25
-x+33=25
subtract 33 from both sides
-x=-8
divide by -1
x=8
the put that answer into original equation
8+y=11
subtract 8 from both sides
y=3
