Three times the sum of a number and four is equal to five times the number, decreased by two. If x represents the number, which

equation is a correct translation of the statement?
1) 3(x + 4) = 5x - 2
2) 3(x + 4) = 5(x - 2)
3) 3x + 4 = 5x - 2
4) 3x + 4 = 5(x - 2)

So 3 times (3 times) the sum of (+) a number and 4 (x,4) is equal to (=) five times the number (5x) decreased by 2 (-2)

the equation would be 3(x+4)=5x-2
so if we solve we get
3x+12=5x-2
12=2x-2
10=2x
5=x
