3x3=9
-2x2=-4
so, 9-4=5
7x4=28
so, 28+5=33
33+3x-1=0
-1
32+3x=0
-32 -32
3x=-32
x=-32/3 or -10 2/3 or 10.67
31
The answer is: 49
7x4=28
A = 4 (7x4) + 8 = 36 (6x4) + 14 = 36
= 53 9x3 + 9x2 + 5x1+ 3x1 27 + 18 + 5 + 3
7x4 equals 28.
=3 x 1 + 4 x 110 + 6 x 11000 = 66443
(7x4) + (4x7) = 28 + 28 = 56

An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
There's no solution, because that expression doesn't ask any question. It just stands for a number, and it's not an equation.
7x4=28
