Answer:
x=8/3
Step-by-step explanation:
1. 3/2=4/x [Rewrite the eqaution]
2. 3x=8[Cross multiply]
3. x=8/3[Just divide]
Answer:
the value of x is 0 and y is -4.
hope it helps uh..
The solutions to the equation
are 3 and -5.
<h3>What is the solution to the equation?</h3>
To solve any equation is to find the solution of the given equation which satisfied the equation.
The given expression is ![\rm (x + 2)^{2} - 2(x + 2) - 15 = 0](https://tex.z-dn.net/?f=%5Crm%20%28x%20%2B%202%29%5E%7B2%7D%20-%202%28x%20%2B%202%29%20-%2015%20%3D%200)
let u = (x +2)
then the equation becomes
![\rm u^{2} - 2u - 15 = 0](https://tex.z-dn.net/?f=%5Crm%20u%5E%7B2%7D%20-%202u%20-%2015%20%3D%200)
by factorizing, we get
(u + 3)(u - 5) = 0
u + 3 = 0, u = -3
u - 5 = 0, u = 5
Since, u = x + 2
So, x + 2 = 5, x = 3
x + 2 = -3, x = -5
Therefore, the solutions to the equation are 3 and -5.

Answer:
73
Step-by-step explanation:
Use the PEMDAS method. Start off with exponents, which is 3x3, which equals 9. Then do multiplication, because it comes before addition. So you multiply 9 by 8 to get 72. Then it says +1 so 72+1 equals 73. (Final Answer)
