Question

Please help me with this!

Answer 1

x = 27

Explanation:

Use the ratio and proportion:

10 = 14

x + 8 2x - 5

just X multiply:

14 ( x + 8 ) = 10 ( 2x - 5 )

-6x = -162

x = -162 / -6

x = 27

Answer 2

10/14 = x+8/ 2x-5, so 10*2x-5= 14*x+8(cross multiplication)
So 20x-50= 14x+112(simplification), so subtract 14x: 6x-50=112, then add 50 to both sides: 6x=162, divide by 6: x=27
