Question

What is the answer 5(x-4)=3x+4

Answer 1

`\boxed{\bold{x=12}}`

Explanation:

Add 20 to both sides

`\bold{5x-20+20=3x+4+20}`

Simplify

`\bold{5x=3x+24}`

Subtract 3x from both sides

`\bold{5x-3x=3x+24-3x}`

Simplify

`\bold{2x=24}`

Divide both sides by 2

`\bold{(2x)/(2)=(24)/(2)}`

Simplify

`\bold{x=12}`

Answer 2

Explanation:

Simplify the left side:

5x - 20 = 3x + 4

Move all terms containing x to the left side of the equation:

2x - 20 = 4

Move all terms not containing x to the right side of the equation:

2x = 24

Divide each term by 2 and simplify:

x = 12
