Answer:
the solution is (-8, 4)
Step-by-step explanation:
Let's use the addition/subtraction method here to eliminate one variable:
-x+y=4
x+3y=4
Combining these two equations results in
4y = 8, so that y = 2. Substituting y = 2 into the second equation, we get:
x + 3(2) = 4, or x = -2.
Then the solution is (-8, 4)
Answer: x=84
Step-by-step explanation: Solve for x by simplifying both sides of the equation, then isolating the variable.
I hope this helps you out. :)
Put the equation in y=mx+b format
Y=-4x-3y
Y+3y=-4x
4y=-4x
Y=-4/4x
Y=-x
The slope is -1
Hope this helps!
Sci = π . 2 . 2 = 12,56 ⇒ 1/2 Sc1 = 1/2 . 12,56 = 6,28
Srec = 6 . 4 = 24
S= 6,28 + 24 = 30,28
the answer is 30,28
ok done. Thank to me :>
