Question

2x+4+x=8+2(3+x)-3 solve for x

Answer 1

Answer:

x = 7

Step-by-step explanation:

$2x+4+x=8+2(3+x)-3\\\\\text{for}\ 2(3+x)\ \text{use the distributive property}:\ a(b+c)=ab+ac\\\\2(3+x)=(2)(3)+(2)(x)=6+x\\\\2x+4+x=8+6+2x-3\\\\\text{combine like terms}\\\\(2x+x)+4=2x+(8+6-3)\\\\3x+4=2x+11\qquad\text{subtract 4 from both sidesi}\\\\3x+4-4=2x+11-4\\\\3x=2x+7\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\3x-2x=2x-2x+7\\\\x=7$

Answer 2

Answer:x=7

Step-by-step explanation:

Use BODMAS

Open bracket first

2x+4+x=8+2(3+x)-3

2x+4+x=8+6+2x-3

2×+x-2x=8+6-3-4

×=7
