Let the number be 'x'
twice the difference of 7 times a number and four means
2(7x-4)=(x+6).............=>14x-8=x+6 =>13x=14 =>x=(14/13)
Ok algebraic expression is 2(7x-4)=(x+6)

the difference of seven times a number and four
7x - 4
NOTE this could also be (4-7x), the question doesn't specify.
Twice the difference of seven times a number and four
2*(7x-4) OR 2*(4-7x)
number increased by six
x + 6
yields the same result
2*(7x-4) = x + 6
OR
2*(4-7x) = x + 6

break it down into little parts:
seven times a number = 7x
the difference of 7x and four = 7x - 4
twice the difference = 2(7x -4)
yeilds = "="
the same number increased by six = x+6
now put all of it together
and solve for x

Let x equal the number you're looking for.
2(7x-4) = 6+x

thrice= 3* distinction of 5 and..., the place ...=x, is 5-x, shop that to the ingredient two times an quantity= 2*y (the place y is the quantity) yields = "=" the quantity larger via 4= y+4 placed all of it jointly now. submit to in recommendations that your x is the 2nd area of the assertion. 3(5-2x) = x+4 (i'm purely changing x with y, right here)
