Answer:
x=10
y=-10
Step-by-step explanation:
multiply first row by 7
14x−21y=350
7x+8y=−10
multiply second row by 2
14x−21y=350
14x+16y=−20
subtract the first row by the second row
−37y=370
solve for y
y=−10
substitute y=-10
14x−21×−10=350
solve for x
x=10
and thats your answer
x=10
y=-10
Answer:
20%
Step-by-step explanation:
Find the difference of both prices.
150 - 120 = 30
Calculate the ratio of the decrease in price to the original price.
30/150 = 0.2
Multiply the decimal by 100 to get your percentage.
0.2(100) = 20
