Question

Using crammers rule solve
6x+5y=2
4x-3y=14

Answer 1

Answer:

x=3.733

y=-4.08

Step-by-step explanation:

6x+5y=2

6x=2-5y

x=2-5y/6

Therefore,

$4x - 3y = \\ \frac{2 - 5y}{6} - 3y = 14 \\ \frac{2 - 5y - 18y}{6} = 14 \\ \frac{2 -23y}{6} = 14 \\ 2 - 23y = 14 \times 6 \\ - 23y = 96 - 2 \\ y = \frac{94}{ - 23} \\ y = - 4.08$

Therefore,

x=

$\frac{2 - 5y}{6}$

y=-4.08

Therefore,

$\frac{2 - 5y}{6} = \\ \frac{2 - 5( - 4.08)}{6} = \\ \frac{2 - - 20.4}{6} = \\ \frac{22.4}{6} = \\ 3.733.....$

Hope it helps you..
