Answer:
x = 0
y = -2
Step-by-step explanation:
6x + 8y = -16
6x - 3y = 6
multiply second equation by -1
-1 × (6x - 3y) = 6 ➡-6x + 3y = -6 now find the sum of this with first equation
-6x + 3y + 6x + 8y = -16 -6 add the like terms (-6x will eliminate 6x)
11y = -22
y = -2 now by using this information we can find the value of x
6x - 3y = 6 replace y by -2
6x -3 ×(-2) = 6
6x + 6 = 6 (-3 multiplied by -2 gives a positive value)
6x = 0
x = 0

Answer:
Step-by-step explanation:
-2/5 - 4/5 + -9/10
= -2/5 - 4/5 - 9/10
= {-2(2) -4(2) - 9)/10
= (-4 - 8 - 9)/10
= -21/10
= -2 1/10
