if `(x/4+1, y-2/4) = (5/4,1/4)` then find the value of `x` and `y`

If [[(x+3y),y],[7-x,4]]=[(4,-1),(0,1)], find the values of x and y.

If y=propx^(4) When x=1000, y=y_(1) then find the value of x so that value of y can be 2y_(1) ,

When x=4 and y=2 find the value of : x+y

When x=4 and y=2 find the value of : x-y

When x=4 and y=2 find the value of : x-:y

The coordinates of the ends of a focal chord of the parabola y^2=4a x are (x_1, y_1) and (x_2, y_2) . Then find the value of x_1x_2+y_1y_2 .

Find the value of x and y : 2x+3y=5,3x+y=4

If x=2 and y=5 find the values of : 3x-4y
