x = 8
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
9 plus 7 equals 144. Generally, x plus y = x(x+y).
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
it equals 3.
(8 + 4) x 5...
x = 8
(3, 5)
5
x=5
3 + x = 8 x = 5
-3
Substitute 5 for x and solve: 8 + 6(5) = ?
x in the equation equals 8 x=8 3*8+11+5*8=75
13
x = 3 and y = 5
