Answer:
Step-by-step explanation:
Find x
8/10 = 5/(5 + x) Cross multiply 8*(5 + x) = 10*5 Combine on the right 8(5 + x) = 50 Remove the brackets on the left. 40 + 8x = 50 Subtract 40 from both sides. 40-40 +8x = 50-40 Combine 8x = 10 Divide by 8 8x/8 = 10/8 Divide x = 1.25 Find y
7/(7 + y) = 8/10 Cross multiply 8*(7 + y) = 10 * 7 Combine the right 8(7 + y) = 70 Remove the brackets. 56 + 8y = 70 Subtract 56 from both sides 56 - 56 + 8y = 70 - 56 Combine 8y = 14 Divide by 8 y = 1.75

y - 8 = -1(x + 9)
y - 8 = -x - 9
y = -x - 1
Answer:
4/7
Step-by-step explanation:
