-7 +2x = x + 8 2x - x = 7 + 8 x = 15
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
If you mean: y^2 + x^2 = 65 and y + x = 7 then the solutions are as follows:- When y = -1 then x = 8 When y = 8 then x = -1
23/8 There are 16 eighths in 2 (2 x 8) plus 7 = 23
This is an unclear equation, actually some sort of addition. (Opposite means negative? Inverse?) 2x + x + (-x) + (-1) = 7 + 2 (-x) ?? 2x - 1 = 7 - 2x 4x = 8 x = 2
If: x + 2/2 + x + 5/7 = 4 Then: x = 8/7
Answer: x = 8/7

-7 +2x = x + 8 2x - x = 7 + 8 x = 15
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.

k = 2 7 + (5 x 2) = 17 (8 x 2) + 1 = 17

You are missing the ")" so I can only guess where it should be:7 + 8(3 by the power of 2) - 2 =7 + 8(3²) - 2 =7 + 8 x 3² - 2 =7 + 8 x 9 - 2 =7 + 72 -2 =77 -2 =75

2(24 + 7) = (2 x 24) + 2 x 7) = 2 x 31 = 62
