Answer:
-14x-1+4x=3
Step-by-step explanation:
it's all in the pic
First substitute the second equation into the first one:
-3x - 3(-5x - 17) = 3
Next distribute the parenthesis:
-3x + 15x + 51 = 3
Then combine like terms:
12x + 51 = 3
Now subtract 51 from each side:
12x = 48
Lastly to get x, divide each side by 12:
x = 4
Now put this into the second equation:
y = -5(4) - 17
Multiply:
y = -20 - 17
And subtract:
y = -37
The solution is (4,-37). Hope this helps!

Answer: 20 6-cents, 30 8-cents, 10 10-cents and 2 20- cents
Step-by-step explanation:
6 cent = x+10
10 cent= x
8 cent= 3x
20 cent=2
6x+60+10x+24x+40
400 divided by 40=X
x=10.
10+10=20/ 6 cents
3x10=30/ 8 cents
x=10/ 10 cents
20 cents= 2.
It has just one solution and dats elimination method
