Here are the steps. I'll try to make them as easy as possible :)
2/3x+1=5
Step 1: Subtract 1 from both sides.
2/x+1-1=5-1
Step 2: Multiply both sides from 3/2
(3/2)*(2/3x)=(3/2)*(4)
And the answer will be 6
x=6

Answer: (1,-1)
Step-by-step explanation:
- You can multiply the first equation by -1
- Add the equations.
- Solve for x, as following:
- Substitute the value of x into any of the original equations and then you must solve for y:
Therefore, the solution is: (1,-1)
Answer:
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
Step-by-step explanation:
<u>Opening the parenthesis and simplifying by combining like terms:</u>
- (6 - y - 4y^2)(-5 + 7y^2) =
- 6(-5) +6(7y^2) - y(-5) -y(7y^2) -4y^2(-5) -4y^2(7y^2) =
- -30 + 42y^2 + 5y - 7y^3 +20y^2 -28y^4 =
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
If you want it estimated it would be .55 which would be 55/100 which would simplify to 11/20
