1 answer:

5 0

Answer is x=13/46.

Simply the equation first, 31-1=92x+4 becomes 30=92x+4.
Flip the equation, 30=92x+4 becomes 92x+4=30.
Subtract 4 from both sides, 92x+4-4=30-4, it then becomes 92x=26.
After that, divide both side since x should be left alone, 92x/92=x , 26/92 - divide it by 2 for a smaller number, and finally it becomes 13/46. And finally x=13/46

Kryger [21]

Answer:

1.53x−14.23

Step-by-step explanation:

simplify:

5.03x−8.03−(3.5x+6.2)

Distribute the Negative Sign:

=5.03x−8.03−1(3.5x+6.2)

=5.03x−8.03−1(3.5x)+(−1)(6.2)

=5.03x−8.03−3.5x−6.2

Combine Like Terms:

=5.03x−8.03+−3.5x−6.2

=(5.03x−3.5x)+(−8.03−6.2)

=1.53x−14.23

5. How many solutions does this system of equations have?

Diano4ka-milaya [45]

Answer:

$\text{\boxed{\sf{D. \ No\ solution}}}$

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

First, you have to substitute of y=-4x-1.

$\Longrightarrow: \sf{[-4x-1=-4x-9]}$

Add by 4x from both sides.

$\Longrightarrow: \sf{-4x-1+4x=-4x-9+4x}$

Solve.

$\Rightarrow:\sf{-1=-9}\\\\\Rightarrow: \sf{(-9)-(-1)=-9+1=-8}\\\\\Rightarrow: \sf{8=0}$

Therefore, the correct answer is "D. No solution".

I hope this helps. Let me know if you have any questions.
