Answer:
x=2
Step-by-step explanation:
Since they are both equal to y set them equal to each other: 2x-3=-8x+17
Subtract 17 from both sides: 2x-20=-8x
Subtract 2x from both sides: -20=-10x
Divide both sides by -10: 2=x

Answer:
300
Step-by-step explanation:
Let x = cost of desktop computer; then x - 250 = cost of laptop computer
converting % to decimals, 9% = 0.09 and 6% = 0.06
Then, 0.09x + (x - 250)0.06 = $300
0.09x + 0.06x - 15 = $300
0.15x = $315
x = $2100
then x - 250 = $1850
Proof: $2100•0.09 + 1850•0.06 = $189 + $111 = $300
