(7x4) + (4x7) = 28 + 28 = 56
28 4x1=4 7x1=7 4x2=8 7x2=14 4x3=12 7x3=21 4x4=16 7x4=28 4x5=20 4x6=24 4x7=28
7x4 equals 28.

28
28 You can use some basic algebra. Call the number you are looking for m, then m/7=4. Multiply both sides of the equation and you have m=7x4=28 Or you can use "brute force" and make a multiplication table of multiple of 7. When you get to 4 you note, as below, that 7x4=28. Of course this is the same answer as above. 1x7= 7 2x7= 14 3x7= 21 4x7= 28 So 28/7= 4
4x7=28 2(4x7)=2x28=56
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
