43 * 24 * 7 * 4 * 22 * 72 . 64 * 16 * 7 * 4 * 4 * 49 = 5619712
9x+4 =x-7 8x=-3 x=-3/8
Do you mean the following? x2 = 4 - 7x If so, then: x2 + 7x = 4 x2 + 7x + 49/4 = 4 + 49/4 (x + 7/2)2 = 65/4 x + 7/2 = ±√65 / 2 x = (-7 ± √65) / 2 So x is equal to (-7 - √65) / 2 and (-7 + √65) / 2
Answer: 7 x 8 + 4 = 60 7 x 8 = 56 56 + 4 = 60
