" 19."6(1-4x)+7(2+5x)=53

Solve: 6(1-4x)+7(2+5x)=53 . Check the result.

Solve each of the following equation and check your answers: (i) 6(1-4x)+7(2+5x)=53 (ii) 5(2-3x)-17(2x-5)=16

From the sum of 6x^(4) - 3x^(3) + 7x^(2) - 5x + 1 and -3x^(4) + 5x^(3) - 9x^(2) + 7x - 2 subtract 2x^(4) - 5x^(3) + 2x^(2) - 6x - 8

Solve each of the following equations and also check your result in each case: 6. 5 x+(19. 5 x-32. 5)/2=6. 5 x+13+((13 x-26)/2) (3x-8)(3x+2)-\ (4x-11)\ (2x+1)=(x-3)x+7) [(2x+3)+(x+5)]^2+[(2x+3)-(x+5)]^2=10 x^2+92

Solve each of the following equations and also check your result in each case: 6. 5 x+(19. 5 x-32. 5)/2=6. 5 x+13+((13 x-26)/2) (3x-8)(3x+2)-\ (4x-11)\ (2x+1)=(x-3)x+7) [(2x+3)+(x+5)]^2+[(2x+3)-(x+5)]^2=10 x^2+92

Let's find the roots of the equations 5x - (4x - 7) (3x - 5) = 6 - 3(4x - 9) (x - 1)

If alpha and beta are the roots of the equation, [1,5][(1,3),(-4,7)]^(2)[(7/19, -13/19),(4/19,1/19)]^(4) [(1,3),(-4,7)]^(2)[(x^2 - 5x + 5),(-3)] = [-4] , then the value of (2 - alpha)(2 - beta) is

If [(2x+y,4x),(5x-7,4x)]= [ (7,7y-13),(y ,x+6)] , then the value of x and y is :
