Answer:

x = −3

Step by step explanation

Let's solve your equation step-by-step.

3 ( 2x + 2 ) + x + 5 = −10

Step 1: Simplify both sides of the equation.

3 ( 2x + 2 ) + x + 5 = −10

( 3 ) ( 2x ) + ( 3 ) ( 2 ) + x + 5 = −10 (Distribute)

6x + 6 + x + 5 = −10

( 6x + x ) + ( 6 + 5 ) = −10 (Combine Like Terms)

7x + 11 = −10

7x + 11 = −10

Step 2: Subtract 11 from both sides.

7x + 11 − 11 = −10 − 11

7x = − 21

Step 3: Divide both sides by 7.

7x  / 7  =  −21  / 7

x = −3

The answer is: x= -27

how to solve
3(2x+2) +x +5 =-10
multiply the numbers in the parentheses
3 x4 +x +5 =-10
multiply 3 x4
12 +x +5 =-10
add the numbers
17 +x =-10
move the constant to the right hand side
x= -10 - 17
calculate the difference
x = -27

Solve these equations using elimination not substitution? 8x + 3y = 13 3x + 2y = 11 15 Points!

Answer:

x = -1, y = 7

Step-by-step explanation:

8x + 3y = 13

3x + 2y = 11

Multiply the first equation by -2 and the second equation by 3. Then add them.

     -16x - 6y = -26

(+)     9x + 6y = 33

--------------------------

       -7x         = 7

x = -1

Now substitute x = -1 in the first original equation and solve for y.

8x + 3y = 13

8(-1) + 3y = 13

-8 + 3y = 13

3y = 21

y = 7

Answer: x = -1, y = 7

=\dfrac{1}{x+2}\cdot\dfrac{x-5}{x-5}+\dfrac{6}{x-5}\cdot\dfrac{x+2}{x+2}\\\\=\dfrac{1(x-5)+6(x+2)}{(x+2)(x-5)}\\\\=\dfrac{7x+7}{x^{2}-3x-10}

Usually, the "simplified" form has the polynomial multiplied out (as immediately above), rather than factored. If you want it factored, you can remove a factor of 7 from the terms of the numerator to get 7(x+1)/((x+2)(x-5)).
