Answer:
44/7
Step-by-step explanation:
First, carry out the indicated multiplication, using the Distributive Property of Multiplication:
-4x + 2(3x – 1) - 12 = 3x + 30 becomes:
-4x + 6x – 2 - 12 = 3x + 30
Next, combine all the x terms and all the constants. We get:
10x - 14 = 3x + 30, or 7x = 44
Dividing both sides by 7 yields x = 44/7.
Answer:
X= -44
Step-by-step explanation:
Multiply parenthesis by 2. Distribute 2 through the parenthesis. Collect like terms. Calculate the difference. Move variable to the left side and change it's sign. Move constant to the right side and change it's sign. Collect like terms. Add the numbers. Change the signs on both sides of the equation. Then you'll get X= -44

Well I don't know !
Let's get together and work it out.
You said that -2x - 3 = -4x + 3
Add 4x to each side: 2x - 3 = 3
Add 3 to each side: 2x = 6
Divide each side by 2 : x = 3 .
-2x-3+4x=-4x+3+4x
2x-3=3
Add 3 to each side;
2x-3+3=3+3
2x=6
Divide each side by 2;
x=3
Hope this helps.
