Question

Solve for x show all work

Answer 1

x=4

Explanation:

we know the ratio of left to right is 2:1 because 6:3=2:1

the horizontal lines are parallel, so the other set of numbers follows the same proportions

`x^(2) +2x+11=2(x+13.5)\\x^(2) +2x+11=2x+27\\x^(2) +2x-2x=27-11\\x^(2) =16\\x=√(16) \\x=4`
