Answer:
Answer is 10
Step-by-step explanation:
you break the equation up to get your answer hope this will help
11111111111111111-111111111-1
8y = 4x -16
-x = -2y -4
Multiply all terms in the second equation by -1:
-x = -2y -4 x -1 = x = 2y +4
Now replace x in the first equation with this.
8y = 4(2y+4)
Simplify:
8y = 8y +16
Because there is an 8y on both sides of the equation, it cannot be solved.
The answer is no solution.
Answer: -5+8 because the difference (-) of -5 and 8 is 8 - (- 5) which can also be expressed as -5+8. All that matters is that 5 stays negative and 8 stays positive.
