Answer:
Read it from left to right, then turn the English into algebra.
"Twice..."
That means 2 times something
"...the sum of a number and 3..."
If we let x be our mystery number, then this gives us 2(x+3)
"is the same as..."
That means it's equal to.
"5 times the number..."
That means 5x.
"...minus 4 times the number"
That means minus 4x.
Put it all together and you get:
2(x+3) = 5x - 4x
Solve this equation for x.

Answer:
-7
Step-by-step explanation:
Let x be the number.
[tex]2(x + 3) = 5x - 1 - 4x[/tex]
[tex]2x + 6 = 5x - 1 - 4x[/tex]
[tex]2x + 6 = x - 1[/tex]
[tex]x + 6 = - 1[/tex]
[tex]x = - 7[/tex]
