Question

Please help me with this geo problem

Answer 1

• x = 1.25
• y = 1.75

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
