x+y=27 x=14 27-14=y y=13
Then y = 3x.
If you mean: y = 3x+1 then the value of y will equal 10
You are basically looking for an equation with an x and y value where when 4 is set as x, y would equal 7. An equation of this is: 3 + x = y when x = 4, then y = 3 + 4 = 7
The y-intercept is the value of a function f when x is equal to zero. So, substitute 0 for x into the equation and find the value of y.
x+y=27 x=14 27-14=y y=13
Then y = 3x.
x = 14
Y = 82x, the value of Y will be 82 times whatever value of x that is chosen
4
The formula to find the value of X would be Y-2X. This would equal to y-9 times 2 X.
2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
Anything you like. x = -4 imposes no restrictions on the value that y can take.
-9
If you mean: y = 3x+1 then the value of y will equal 10
