y=x+4
x = y - 4 when x = 16, the equation becomes 16 = y - 4 so that y = 20

given: x - 4 = -y or, -y = x - 4 or, y = -(x - 4) or y = -x + 4 or y = 4 - x i.e. for x > 4, the equation x - 4 = -y is true.
x + y = 4 or y = -x + 4 To get X-intercept, make y = 0, then 0 = -x + 4, or x = 4To get Y-intercept, make x = 0, then y = -0 + 4, or y = 4
x^(4)*y*x^(5)*yMultiply x^(4) by y to get x^(4)y.(d)/(dx) x^(4)*y*x^(5)*y=x^(4)y*x^(5)*yMultiply x^(4)y by x^(5) to get x^(9)y.(d)/(dx) x^(4)*y*x^(5)*y=x^(9)y*yMultiply x^(9)y by y to get x^(9)y^(2).(d)/(dx) x^(4)*y*x^(5)*y=x^(9)y^(2)To find the derivative of x^(9)y^(2), multiply the base (x) by the exponent (9), then subtract 1 from the exponent.(d)/(dx) x^(4)*y*x^(5)*y=9x^(8)y^(2)The derivative of x^(4)*y*x^(5)*y is 9x^(8)y^(2).9x^(8)y^(2)
x-y=4 x=y+4
x=9; y=4; x=x+y; #x=13;y=4; y=x-y; #y=13-4=9; x=x-y; #x=13-9=4;
If that's y times 4, the answer is 4y
Evaluate x/y when x = 4 and y = 4. x/y = 4/4 = 1/1 = 1

x=4 y=x+3 y=4+3 y=7
2x + 4 = y ...............2x + 4 = y ....................2x + 4 = y .............2*(-6)+ 4 = y x - y = 2 .......<=> ...x - 2x - 4 = 2 .....<=> ...x = -6......... <=>.... x = -6 ..............<=> y = - 8 x = - 6
If X+Y=5;X=4, then x=4 and y=1
