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

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
