14. Solve for the value of x in this equation.
2x - (4x + 1) = 3x - 6
2 answers:
Step-by-step explanation:
2x-(4x+1)=3x-6
- 2x-4x-1=3x-6
- -2x-1=3x-6
- 3x+2x=6-1
- 5x=5
- x=5/5
- x=1
Answer:
-1.4 = x
Step-by-step explanation:
Step 1: Combine like terms and subtract the 3x from 2x.
-x - (4x + 1) = - 6
Step 2: Combine more like terms. (and remove parentheses)
-5x + 1 = - 6
Step 3: Combine different like terms.
-5x = -7
Step 4: Divide it out.
x = - 1.4

For example:
(4/9) x=8
Now can solve this equation multiplying each side by 9/4.
(9/4)(4/9)x=(9/4)8
x=18
To check:
(4/9)(18)=(4*18)/9=72/9=8
