14/3 x 17/7 = 238/21 = 34/3 = 11 and 1/3
(14 + 3) x (17 - 7) = 17 x 10 = 170
1 x 177, 3 x 59.
177 x 177 = 1772 = 31,329
x = 7.375 because... 3 over 2x -15 = -12 3 = -12(2x-15) 3 = -24x + 180 0 = -24x + 177 24x = 177 x = 7.375
3/14 = x/84 3 times 84 = x times 14 x = 3 x 84 / 14 = 18
x + y = 66 where x > y 2x - y = 177 rearrange the top equation: y = 66 - x substitute into the bottom: 2x - (66 - x) = 177 2x - (-x) - 66 = 177 2x + x - 66 = 177 2x + x = 111 3x = 111 x = 111/3 = 37 substitute back into the first equation: 37 + y = 66 y = 66 - 37 = 29
1 x 177, 3 x 59 = 177
1 x 177, 3 x 59.
1 x 177, 3 x 59.
1 x 177 3 x 59
177 = 180 - 3 and 3 goes into 180 so not a prime (59 x 3 = 177)
59 x 3= 177
3 x 59 = 177
177 x 177 = 1772 = 31,329
1 x 1770, 2 x 885, 3 x 590, 5 x 354, 6 x 295, 10 x 177, 15 x 118, 30 x 59 = 1770
11
x+3=14 x+3-3 = 14-3 (subtract 3 from both sides to solve for x) x = 11
x = 7.375 because... 3 over 2x -15 = -12 3 = -12(2x-15) 3 = -24x + 180 0 = -24x + 177 24x = 177 x = 7.375
