The answer is 270 , I multiplied 15 by 18 and got 270
First think you need to add $1.23 and$1.54and your sum will be $2.77 ($1.54+$1.23=$2.77)
X+y+z=92
y=3x
z=2x-10
subsitute
x+3x+2x-10=92
6x-10=92
add 10 to both sdies
6x=102
divide by 6
x=17
subsitute
y=3x
y=3(17)
y=51
z=2x-10
z=2(17)-10
z=34-10
z=24
x=17
y=51
z=24
the numbers are 17,51,24
