Answer:

x=-3, y=1. (-3, 1).

Step-by-step explanation:

-x+5y=8

3x+7y=-2

----------------

3(-x+5y)=3(8)

3x+7y=-2

--------------------

-3x+15y=24

3x+7y=-2

------------------

22y=22

y=22/22

y=1

-x+5(1)=8

-x+5=8

-x=8-5

-x=3

x=-3

1.3n-0.03=-9 (solve for n) grade lvl. 7

bazaltina [42]

Hello from MrBillDoesMath!

Answer:

-6.9

Discussion:

1.3n - 0.03 = -9 => multiply both sides by 100

130n - 3 = -900 =>

130n = -900 +3 = -897 => add 3 to both sides

n = -897/130 =>

n = - (69 * 13)/ (10*13) =>

n = - 69/10 = - 6.9

Thank you,
