Answer:

[tex]x=4[/tex]

Step-by-step explanation:

[tex]4x + 4 = -7 +2x +19[/tex]

[tex]4x + 4 = 2x +12[/tex]

[tex]4x-2x=12-4[/tex]

[tex]2x=8[/tex]

[tex]x=8 \div 2[/tex]

[tex]x=4[/tex]

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 .
