20x+x-2=4 rational equation
2 answers:
Answer:
x = 2/7
Step-by-step explanation:
Step 1: Write equation
20x + x - 2 = 4
Step 2: Solve for <em>x</em>
- <u>Combine like terms:</u> 21x - 2 = 4
- <u>Add 2 to both sides:</u> 21x = 6
- <u>Divide both sides by 21:</u> x = 6/21
- <u>Simplify:</u> x = 2/7
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
20(2/7) + 2/7 - 2 = 4
40/7 + 2/7 - 2 = 4
42/7 - 2 = 4
6 - 2 = 4
4 = 4
Answer:
x = 2/7
Step-by-step explanation:
Collect like terms:
20x + x = 21x ----> 21x - 2= 4
Move the constant to the right hand side and change the sign of the constant:
21x = 4 + 2
Calculate:
21x = 4 + 2 ---> 21x = 6
Divide both sides by 21:
21/21 and 6/21 = 2/7
Solution:
x = 2/7 or x= 0.285714
