The answer is y+3-3=7+3 y=10.
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
(3, 1)
Well what does y equal? If y equals 7 the 3+7=10
x = -3, y = 7
X=-3/7
xy^(2) - y + 2x = -3 And y = 7 Substitute for 'y' Hence x7^(2) - 7 + 2x = -3 49x + 2x - 7 = -3 51x = 4 x = 4/51 = 0.078431372....
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
(3, 1)
3 + Y where Y = 7 Substitute 7 for Y (because Y = 7) so: 3 + 7 = 10.
Y = x - 7
Well what does y equal? If y equals 7 the 3+7=10
x = -3, y = 7
y=3*+7.what does the * mean?
X=-3/7
x=5 y=-3
x=7 y=4
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
