Solve the system for x: 6x - 5y = 8 2x + 9y = 24

Gennadij [26K]

Answer:

x = 3

Step-by-step explanation:

$\left \{ {{6x-5y=8} \atop {2x+9y=24}} \right.$

I'm going to use the method of elimination by multiplying the second equation by -3:

$\left \{ {{6x-5y=8} \atop {-6x-27y=-72}} \right.$

Then I can eliminate x:

-32y = -64

To solve for y, I'd simply divide:

y = 2

Because I now have y = 2, I'll just plug in 2:

6x - 5(2) = 8

6x - 10 = 8

6x = 18

x = 3

Hopefully I helped :)

What are significant figures?

scZoUnD [109]

Answer:

Significant Figures are the figures in a number that are meaningful and are digits with no zeros. Those zeros can be traced in a number like “320”, or “5670.0045”. Those zeros are not counted when counting the significant figures.
