Answer:
+ 12
Step-by-step explanation:
8 - (- 4) = 8 + 4 = 12
So our two equations are y=-8x-4 and y=-16, and since in both equations, something equals the same y, those two are the same. So we can combine the two into -16=-8x-4. In the question, they are asking to solve for x. So to do that, you need to isolate your variable. Now for solving algebraic equations, you use reverse PEMDAS (SADMEP), meaning you add 4 to both sides to clear the -4 one the rights side to get -12=-8x. Then you divide both sides by -8 to get 12/8, which simplifies to 3/2.
Answer:
16

Answer:
If the question you are asking looks like this (5x*8x)(-3+9) then the answer is 240xsquared so the tiny 2 would be over the x
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
Given
2y - 3 = 2y + 4 ( subtract 2y from both sides )
2y - 2y - 3 = 4 ( add 3 to both sides )
0 = 7 ← not possible
This indicates that the equation has no solution
