Answer:
Step-by-step explanation:
<u>Add:</u>
- 4x² - 2x + 6 + 2x² + 4x - 1 = 6x² + 2x + 5
<u>Subtract:</u>
- 6x² + 2x + 5 - 5x² - 2x + 4 = x² + 9
Answer:
x=1
Step-by-step explanation:
First find a common denominator between 7 and 4 which is 28, Multiply both equations by 28 eliminating the denominators so now you have theses two equations: 4(2x + 12) = 7(3x + 5) distribute these equations to get:
8x + 48 = 21x +35 now you want to get the x's on one side so 8-21 = -13 which as an equation so far would be -13x + 48 = 35 now do 35-48 = -13 so you can have 13x alone on one side. Your final equation now before you solve is
-13x = -13 the divide -13 by -13 to get 1.
Hope this helps you understand it better
X ≥ 90 + 3x
You simplify the right side, then subtract 180 from both sides, then multiply by negative one.
Answer:

Step-by-step explanation:
4/5
Step-by-step explanation:
9x+1=5
or, 9x=5-1
or, 9x=4
therefore x=4/5
