There is no symbol between 7a and b2: is there meant to be?
7 x 4 = 28
6 x 6 = 36
28 x 36 = 1008
1008/9 = 112
28 + 36/9 = 32
It is: (7*4)-(2*2)+1 = 25

It's a linear equation in ' a '.When you see one of these, it often happens that curiosity overtakes you, and you begin to wonder about the numerical value of ' a ' that makes the equation true. Let's find out:3a - 7a + 12 = 323a - 7a = 20-4a = 20a = 20 / (-4) = -5The equation is true if ( a = -5 ).
(7 * 4) - 4 - 11 = 13
Assuming the value you want to multiply by 40% is in cell B2 you could use any of these formulas: =B2*40% =B2*0.4 =B2/100*40 =B2/10*4
7a 7a * 4 = 28a 7a * 7b = 49ab
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
It is: (7*4)-(2*2)+1 = 25

It looks like you've taken 'a' away from '7a' three times, so you probably have 4 of them left.
