√175 = √(25 x 7) = √(52 x 7) = 5√7
Unless you have a value for x, it cannot be simplified any further so it will be: x - 9
776
-12
'X-7 plus 23-6' can be simplified and expressed as: 'x+10'
-2
28 = 36 x 7/9 = 36/9 x 7 = 4 x 7
360 x 7 = 2520 2520 ÷ 9 = 280
(7/9) x (4/63) = (1/9) x (4/9) = 4/81
5/7 x 9/10 = 9/14
3/5 x 7/9 is 7/15
Simplified: 5x + 35 Solved: x = -7
9 x 3/7 = 9/1 x 3/7 = 9x3/1x7 = 27/7 = 36/7
28/9 x 4/7 = 1 and 7/9
6/7 x 9/9 = 54/63 80/9 x 7/7 = 560/63 54/63 + 560/63 = 614/63
6x-7=8x+9 bring the x over -7=2x+9 take the 9 over -16=2x divide both sides by 2 x=-8
That's the same as 7/9 x 10/9 = 70/81
