Y=-2x - 6
y = x +9
solve each system of equations using substitution or elimination.

x=-7/2, y=1

Step-by-step explanation:

y=-2x-6

y=x+9

I'm going to use elimination.

2y=2x+9

y=-2x-6

3y=3

y=1

Enter y into one of the equations to find x.

2=2x+9

2x=-9+2

2x=-7

x=-7/2

step-by-step explanation:

$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
