What dose x equal 4x + 4 = -7 +2x +19

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+4=−7+2x+19

4x+4=(2x)+(−7+19)(Combine Like Terms)

4x+4=2x+12

4x+4=2x+12

Step 2: Subtract 2x from both sides.

4x+4−2x=2x+12−2x

2x+4=12

Step 3: Subtract 4 from both sides.

2x+4−4=12−4

2x=8

Step 4: Divide both sides by 2.

2x/2 = 8/2

Description:

The first step is to Simplify both sides of the equation, when you do it correct and follow the steps above you equation will end up 4x+4=2x+12. For steps 2 Subtract 2x from both sides, when you do it correct your equation will end up like 2x+4=12. For step 3 you  Subtract 4 from both sides, when you do it correct equation will end up like 2x=8. Last step is to Divide both sides by 2, when you do it correct your answer will come as x=4 .

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
