Solve the equation (If possible please show work)

deff fn [24]

Answer:

$x=-3$

Step-by-step explanation:

So we have the equation:

$-2(-x-4)+3=-7-4x$

First, distribute the left side:

$-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x$

Add values on the left side:

$2x+11=-7-4x$

Add 7 to both sides. The right side cancels:

$(2x+11)+7=(-7-4x)+7\\2x+18=-4x$

Subtract 2x from both sides. The left side cancels:

$(2x+18)-2x=(-4x)-2x\\18=-6x$

Divide both sides by -6:

$(-6x)/-6=18/-6\\x=-3$

Therefore, x equals -3.

If an arithmetic progression satisfies U4=7 , U8=15 .Find U10

Alja [10]

Answer:

U10 = 19

Step-by-step explanation:

The sequence is $Ux=(x*2)-1$

x is the coefficient to U.

So, $U10=(10*2)-1$

Which means $U10=20-1$

Which means $U10=19$

And there is your answer.

Hope this helps. Have a nice day.
