Answer:
is there a multiple question?
Step-by-step explanation:
uh- this is the correct way to answer the problem....
−4x+12=−6x
Step 1: Add 6x to both sides.
−4x+12+6x=−6x+6x
2x+12=0
Step 2: Subtract 12 from both sides.
2x+12−12=0−12
2x=−12
Step 3: Divide both sides by 2.
=
x=−6
Answer:
The last one is incorrect
Answer:
value of x = -2
value of y = 1
Step-by-step explanation:
here's the solution :-
the given equations are :
=》-4x - 4y = 4
=》6x + 4y = -8
adding both equations, we get ;-
=》-4x - 4y + 6x + 4y = 4 - 8
=》2x = -4
( positive and negative 4y get eliminated )
=》x = -4 / 2
=》x = -2
plugging the value of x in equation 2 we get ,
=》6x + 4y = -8
=》(6 × -2) + 4y = -8
=》-12 + 4y = -8
=》4y = -8 + 12
=》y = 4 / 4
=》y = 1
Answer:
A) 4
Step-by-step explanation:
10 divided by 2 = 5
15 divided by 3 = 5
so 20 divided by 4 = 5
