Answer:

x=5

Step-by-step explanation:

x-3x can be simplied to -2x and 3-9 can be simplied to -6

-2x+4=-6

Substract 4 from both sides

-2x=-10

Divide both sides by -2

x=5

Answer:

x=5

Step-by-step explanation:

x-3x+4=3-9\\x-3x+4=-6\\-2x+4=-6

<em>Subtract 4 from both sides</em>

-2x+4-4=-6-4\\-2x=-10

<em>Multiply both sides by -1</em>

2x=10

<em>Divide both sides by 2</em>

x=5

How do you solve the system 3x-y z=5, x 3y 3z=-6, and x 4y-2x=12?
dlinn [17]
3x - y + z = 5 . . . (1)
x + 3y + 3z = -6 . . . (2)
x + 4y - 2z = 12 . . . (3)

From (2), x = -6 - 3y - 3z . . . (4)
Substituting for x in (1) and (3) gives
3(-6 - 3y - 3z) - y + z = 5 => -18 - 9y - 9z - y + z = 5 => -10y - 8z = 23 . .  (5)
-6 - 3y - 3z + 4y - 2z = 12 => y - 5z = 18 . . . (6)

(6) x 10 => 10y - 50z = 180 . . . (7)
(5) + (7) => -58z = 203
z = 203/-58 = -3.5

From (6), y - 5(-3.5) = 18 => y = 18 - 17.5 = 0.5
From (4), x = -6 - 3(0.5) - 3(-3.5) = -6 - 1.5 + 10.5 = 3

x = 3, y = 0.5, z = -3.5

Please help me with my homework.
Blababa [14]

Answer:

-3x + 6

Step-by-step explanation:

-3(x - 2) to find the equivalent of this expression, we need to multiply inside the parenthesis with -3 (with both x and -2)

-3(x - 2 = -3x + 6 (two negative expressions multiplied results in positive)
