Answer: x1 = -2, x2 = 3/4

Step-by-step explanation:

4x^2 + 5x -6 = 0

4x^2 + 8x -3x -6 = 0

4x(x+2)-3(x+2)=0

(x+2)(4x-3) = 0

x+2 = 0: x = -2

4x-3 = 0: x = 3/4

Solve each linear equation x+4y=18 x+8y=38
suter [353]

Answer:

Answer:  {x = -2 , y = 5

Step-by-step explanation:

{x + 4 y = 18 | (equation 1)

{x + 8 y = 38 | (equation 2)

Subtract equation 1 from equation 2:

{x + 4 y = 18 | (equation 1)

{0 x+4 y = 20 | (equation 2)

Divide equation 2 by 4:

{x + 4 y = 18 | (equation 1)

{0 x+y = 5 | (equation 2)

Subtract 4 × (equation 2) from equation 1:

{x+0 y = -2 | (equation 1)

{0 x+y = 5 | (equation 2)

Collect results:

Answer:  {x = -2 ,  y = 5
