X+8y=15 -x-10y=-19

Its for math

Simplifying

x + 8y = 15

Solving

x + 8y = 15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8y' to each side of the equation.

x + 8y + -8y = 15 + -8y

Combine like terms: 8y + -8y = 0

x + 0 = 15 + -8y

x = 15 + -8y

Simplifying

x = 15 + -8y

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
