Given 2x - 9y - 12 = 0, express 5x - 4y + 7 = 0 in terms of x only

olga2289 [7]

Answer:

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = $-1\frac{1}{3} + \frac{2}{9} x$

Therefore...

5x - 4y + 7 = 0

5x - 4( $-1\frac{1}{3} + \frac{2}{9} x$ ) + 7 = 0

5x + $5\frac{1}{3}$ - $\frac{8}{9} x$ + 7 = 0

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0
