What error did Lucia make? When Lucia solved the second equation for x, she subtracted 2y from both sides,
O When Lucia solved for the value of y, she treated - 2y as 2y.
When Lucia solved for the value of x, she added 18 to both sides,
o When Lucia solved the second equation for x, she treated -2(-9) as 18 instead of -18.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30
