17 x 365 x 55 = 341,275
X = 88/7 = 12.571 (3dp)

8x+7=55 8x=55-7 [subtract 7 from both sides] 8x=48 x=48/8 [divide both sides by 8] x=6

Let the number be x and so if 2x+5 = -55 then the value of x is -30
57
X = 88/7 = 12.571 (3dp)
The answer is 18 - consider that a division sum is always a fraction in the form x over y. x/55 is equal to 18/55 - simply replace the 18 for an x, and then replace back.
X=6

8x+7=55 8x=55-7 [subtract 7 from both sides] 8x=48 x=48/8 [divide both sides by 8] x=6
to solve this answer plz go to the bottom of this : 55 x 1 = 55 2 x 55 = 110 3 x 55 = 165 4 x 55 = 220 5 x 55 = 275 6 x 55 = 330 7 x 55 = 385 8 x 55 = 440 9 x 55 = 495 10 x 55 = 550 11 x 55 = 605 12 x 55 = 660 THANKS !
3x+130+65 = 360 3x+195 = 360 3x = 360-195 3x = 165 x = 55
This is an example of a quadratic equation. It has many solutions depending of the value of x. Its solution would commonly be shown as a graph. For example, if x = 2 then the answer is 22 + 16x2 +55 = 4+32+55 = 91. if x = 3 then the answer is 32 + 16x3 + 55 = 9+48+55 = 112. [but check my arithmetic!]
