Answer: y=-1 and x=2

Step-by-step explanation:

-9x+8y=-26

-9x-6y=-12

Subtract

14y = -14

Divide by 14

Y=-1

Substitute y=-1 into the equation

-9x-6(-1)=-12

-9x+6=-12

-1/2+ 7/8- 1/10<br><br> Hint: rational numbers
ki77a [65]

After solving -\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\ we get \frac{11}{40}

Step-by-step explanation:

We need to solve the following expression:

-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\

Solving the above expression we need to find the LCM of denominators: 2,8,10

The LCM of 2,8,10 is 40

-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\=\frac{-1*20+7*5-1*4}{40}\\=\frac{-20+35-4}{40}\\=\frac{11}{40}

So, after solving -\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\ we get \frac{11}{40}
