2x+3y-4z+3x-5y+z
Help me pls

Step-by-step explanation:

You'll only have to combine the same like variable and the result will be

5x-2y-3z

Simplified expression: 5x-2y-3z

Step-by-step explanation:

Add up all the variables

2x+3x=5x

-5y+3y=-27

-4z+z=-3z

47 - 90 = 43

43 - 180 = x

x = 137

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
