13 + 52 = 65
-52 + 39 = -13
-52x + 3 = 7 -52x + 3 = 7 -3 -3 -52x = 4 /52 /52 -x = 1/13 /-1 /-1 x = -1/13
1/4 + 2/13 = 13/52 + 8/52 = 21/52
subtraction; 80-y= 52. 28+52 =80
7q+13 = 52 7q = 52-13 7q = 39 q = 39/7
(x + 4)(x + 13)
7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13
x + 52 + 2y + 35 = 3 x + 2y = 3 - 52 -35 x + 2y = -84 Infinite number of solutions, are you sure you posted the correct equation?
To solve for x, we'd have to know what this expression equals.
13+c = -39 c = -39-13 c = -52
95 plus 52 plus 95 plus 52 equals 294.
Use the quadratic formula. In x2 + 12x + 13 = 0, a = 1, b = 12 and c = 3. The formula is:-b +/- √(b2 - 4ac)----------------------2aThus, x = [-2 +/- √(122 - 4(1)(13))]/2(1) = [-2 +/- √(144 - 52)]/2 = [-2 +/- √92]/2 = -1 +/- √23.
