Answer:

Emanuel made huis mistake in first step and step 1 is incorrect.

Step-by-step explanation:

The given expression is

(\frac{3}{5})(\frac{4}{9})(-\frac{1}{2})

It can be written as

\frac{3}{5})(\frac{4}{9})(\frac{-1}{2}

Step 1: (\frac{(3)(4)(-1)}{(5)(9)(2)})

Emanuel used negative sign with both numbers 1 and 2. Therefore the first step of Emanuel is incorrect.

Step 2: \frac{-12}{90}

Step 3: \frac{-2}{15}

Therefore Emanuel made huis mistake in first step and step 1 is incorrect.

Answer:

5) x = -1

6) x = 2

Step-by-step explanation:

5) 5 + 2x + 6 = x + 10

   2x + 11 = x + 10

   2x + 1 = x

   1 = -x

   -1 = x

6) (9x + 7) + (-3x + 20) = 39

    6x + 27 = 39

    6x = 12

     x = 2

Step-by-step explanation:

If you simplify the equation 2y=14-2x and divide everything by 2 you get y=7-x or y=-x+7 which equals the second equation perfectly so there are infinitely many solutions to the system of equations

What is the solution to this system of equations?
antoniya [11.8K]

Answer:

c

Step-by-step explanation:

Since both equations express y in terms of x we can equate the right sides

3x + 5 = - x + 3 ( add x to both sides )

4x + 5 = 3 ( subtract 5 from both sides )

4x = - 2 ( divide both sides by 4 )

x = - 0.5

substitute x = - 0.5 in either of the 2 equations

using y = - x + 3 then y = 0.5 + 3 = 3.5

solution is (- 0.5, 3.5 ) → c
