Answer:
add both sides ny 9.6 and divide both sides by 3.2, hope this helps!
Answer:
4. y = -x + 8
9. y = 3/2x + 15
16. y = 1/2x -5
20. y = -3/5x + 16
13. y = -1/2x + 1
14. y = 3/4x - 2
Step-by-step explanation:
4. 5=3(-1)+b = 8
9. 6=-6(3/2)+b=15
16.
-2= (1/2)6 + b = -5
20. 
19 = -3/5(-5) + b = 16
Answer:
Step-by-step explanation:
hello :
6x+5y=-20.....(*)
-6x-10y=25.....(**)
add(*) and(**) : -5y=5 so y= -1
multiply (*) by 2 : 12x+10y=-40 ...(***)
now add(**) and (***) : 6x=-15 so x = -15/6 = -5/2
