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

You can easily find the decimal of a fraction by doing long division or inserting the fraction in a calculator (which teachers usually allow their students to use a calculator even on tests... unless if the test is about long division, etc).
Long division is pretty hard to do without a pen and paper, but the steps to do long division are: divide the number on the right by the left number - multiply the number on the left by the top number - subtract the number on the right by the number below it - bring down, and then repeat if you can.
