-2x-y=3 ...(1)
x+2y=4 ...(2)
multiply (2) by 2 and add to (1)
-2x-y+2x+4y=3+8
3y=11
y=11/3
from (2)
x=4-2y=4-2(11/3)
or x=4-(22/3)
=(12-22)/3=-10/3
45 degrees? I may be wrong. 360/8=45
-214 x -412 = 88,168
“Product” means the answer you get from multiplying two or more numbers together.
* Tip: A negative number times another negative number equals a positive.
Hope this helps!
Answer:
1. move the constant to the right hand side to change its sign.
2.add the numbers.
3. using the absolute value definition rewrite the absolute value equation as two separate equations.
4.slove the equation for X
Step-by-step explanation:
it has two solutions
x=8
x= -9
the answer should be X1= 9, x2 =8
Choice B is the correct answer. You can do this yourself by graphing on Desmos.
