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
Answer:
y=1.58
Step-by-step explanation:
7=4(3y-3)
Simplify the distributive property.
7=12y-12
Add 12 to both sides.
19=12y
Divide 12 on both sides.
1.58=y
