<em>First evaluate the operations inside of the brackets</em>
-8 + 2[5 + (-4 + 1)2] <em>evaluate (-4 +1) because it is surrounded by parenthesis</em>
-8 + 2[2 + (-3)2]) <em>multiply (-3)2
</em>-8 + 2[2 - 6] <em>subtract 2 - 6 because it is surrounded by the brackets (parenthesis)
</em>-8 + 2(-4) <em>multiply 2(-4)</em>
<em>-8 - 8
-16</em>
Answer: do you have the graph?
Step-by-step explanation:
X = -2 + y
-16x - 3y = -25
Let's substitute x into the second equation, since the first equation already tells us what x is.
Multiply -16 by x, which is (-2 + y)
-16(-2 + y) -3y = -25
Simplify.
32 -16y -3y = -25
Simplify. Get the variable on one side.
-19y = -57
Divide both sides by -19 to solve for the variable.
y = 3
Now plug y = 3 into one of the equations to find x. I'll use the first equation, since it's easier.
x = -2 + y
x = -2 + 3
x = 1
The answer is x= 1, y =3, which may be written as (1, 3). Hope this helps.
It would be x + y + 64
You subtract the -x from the 2x
