It seems there may be a typo or formatting issue in the equation you provided. If you meant to write a mathematical expression, please clarify it. For instance, if you meant "3x + 57 = 47," you would solve for x by first subtracting 57 from both sides to get 3x = -10, and then dividing by 3 to find x = -10/3 or approximately -3.33. Please provide the correct equation for a more accurate solution.
3x7
x=7 look at the bottom for the reason: First, when a number and a variable are placed next to each other it means to multiply the 2. (example- what is 3x if x=7 ? Well, 3x7=21 so, 3x=21) so, 5x + 2x + 3x + 10x = 140 20x = 140 40/20 = 7 so, (5x7) + (2x7) + (3x7) + (10x7) = 140 so, 35 + 14 + 21 + 70 = 140
I think 7x3 is = to 21
7x3 or 3x7, which is all you can do to multiply to get 21.
You take 3x7+4=25 :)
It is: 5+(3*7) = 26

We don't know and can't calculate it, until we're given the value of 'x'.
3(7 + 2) = 3x7 + 3x2 is an example of the distributive law.The distributive law connects multiplication and addition.

y = -1/(3x7 + 2x - 9)y = -(3x7 + 2x - 9)-1y' = -(-1)(3x7 + 2x - 9)-2(3x7 + 2x - 9)'y' = (3x7 + 2x - 9)-2(21x6 + 2)y' = (21x6 + 2)/(3x7 + 2x - 9)2
It depends! What is the value of N? Example If n= 3, the answer would be 11 (3n= 3x3=9 the plus the 2) Example 2 If n=7, ten the answer would be 23 (3n= 3x7=21 plus the 2wouldbe 23) Hope this helps
3, 7, 21. 3x7 is the only equation that equals 21, and so these are the only factors of 21.
3x7 = 21
To find 6x7 using 3x7, you can simply double the result of 3x7. This is because multiplication is distributive over addition, meaning that multiplying a number by a sum is the same as multiplying the number by each addend and then adding the products. In this case, 6x7 can be thought of as (3+3)x7, which equals 3x7 + 3x7, or 21 + 21, which equals 42.
