Answer:
Step-by-step explanation:
(-6,8)...x = -6 and y = 8
lets start subbing
5x + 3y = -6
5(-6) + 3(8) = -6
-30 + 24 = -6
-6 = -6
so (-6,8) IS a solution to this equation
2x + y = -4
2(-6) + 8 = -4
-12 + 8 = -4
-4 = -4
so (-6,8) IS a solution to this equation
A. It is the only solution to the system
The answer is 7850 centimeters since 1m=100 cm. 78.5*100=7850
Remark
The order is not quite correct.
- 7 + (-11 * 5 - - 7) ÷ - 6
The - - 7 becomes a plus
- 7 + (- 55 + 7) ÷ -6
This is where the real problem is. -55 + 7 goes down. This gives - 48
- 7 + [( - 48) ÷ - 6]
You do the division by - 6 before adding. Adding - 7 to the result of the division is your very last step. Think BedMas.
-7 + (8)
The 8 is the result of the division. -48/-6 = 8. the -7 and the 8 are added. You get 1.
