Question

Solve by elimination: 3y-4x=29 2y+5=4

Answer 1

The solution is x = -61/8 and y = -1/2.

Step-by-step explanation:

The given equations are -4x + 3y = 29 and 2y + 5 = 4

   Step 1 : There is no x term in the second equation.

   Step 2 : Solve for y, 2y = 4 -5

                                      y = -1/2

   Step 3 : Substitute y = -1/2 in first equation and solve for x.

   Step 4 : -4x + 3(-1/2) = 29

                 -4x -(3/2) = 29

                 -8x -3 = 29$\times$2

                 -8x = 58 + 3

                  x = -61/8
