0.79 x 4.3 = (79 x 43)/1000 = 3397/1000 = 3.397
2 x 43 x (-6) = -516
13-3x = 43 -3x = 43-13 -3x = 30 x = -10
the three numbers are: x - 2, x, x+2 the sum of their squares: (x-2)2+ x2 + (x+2)2 = x2 - 4x + 4 + x2 + x2 + 4x + 4 = 3x2 + 8 = n*1111 n= 1,2,3 ... 9 x= sqrt((n*1111 - 8)/3) n = 5, so x = 43 or -43 and the numbers are: -45, -43, -41 or 41, 43, 45
43
5x + 3y = -7x = 43 - 8y5x + 3y = -75(43 - 8y) + 3y = -7215 - 40y + 3y = -7215 - 37y = -7215 -215 -37y = -7 - 215-37y = -222-37y/-37 = -222/-37y = 6x = 43 - 8yx = 43 - 8(6)x = 43 - 48x = -5Thus, (-5, 6) is the solution of the given system of the linear equations.
43 greater than x - 43+x 43 greater than x plus 35 - 43+x+35 43+35+x=78+x
1 x 43, 43 x 1 (43 is a prime number).
