Find an equivalent system of equations for the following system X + 2y = 2
- 4x + 4y = -8
x + 2y = 2
-4x - 2y = 10
Ox+2y=2
5x + 4y = 8
x+2y=2
5x - 2y = 10
x+2y=2
N2 = -8

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

the answer is two. hope this !

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

where is the picture
