x + 7x3 -5=20
x + 21 - 5 = 20
x + 21 - 5 + 5= 20+5
x + 21 =25
x + 21-21=25-21
x=4
If you remember BEDMAS...(brackets, equations, division, multiplication, addition, subtraction) you should be able to do well in algebra. hope this helps...it's been a long time, but I believe this is what you are looking for

I think it is x-5+21=20 so then x = 4

[x+ (7*3)] - 5 = 20
x + 21 - 5 = 20
x = 4
confusing statement.... are they saying the sum of x and 7, times 3, or x and (7 times 3)?
i guess it's the 2nd one, since there is no comma. :)

3(x+7)-5=20
to solve:
3x+21-5=20
3x+16=20
3x=4
x=4/3 or 1 1/3

Our 2 products are x and y. at the same time, they could desire to upload as much as the size of the completed rope, it relatively is seventy 5 ft. x + y = seventy 5 Now, to ascertain what y is, in terms of x, we could desire to get y by itself on the left area ("resolve for y"). We try this by subtracting x from the two facets of the equation: y = seventy 5 - x So our answer is that the different piece of rope is seventy 5-x ft.
