The correct answer is true:)
1. Take away the parentheses. x+2x+40+3x-50=15002
2. Add the X’s together.
x+2x+3x= 6x —> 6x+40-50=15002
3. Subtract 50 from 40.
40-50= -10 —> 6x-10=15002
4. Move -10 to the right hand side to make it positive.
6x=15002+10
5. Add 15002 and 10 together.
6x=15012
6. Divide 15012 by 6. Which makes the answer X=2502
2a+3c=22.00 ......equation 1
a+4c=18.50 =>2a+8c=37.00 .....equation 2
subtract equation one from equation two:
5c=37-22=15
c=3
a+4*3=18.50 =>a=6.50
for the Hu family: 3*6.50+1*3.00=22.50 dollars
