Solve the equation. 2x - 4 = -10?

2X - 4 = - 10

add 4 to each side

2X - 4 + 4 = - 10 + 4

2X = - 6

divide each sides integers by 2

(2/2)X = - 6/2

X = - 3

------check in original equation

2(- 3) - 4 = - 10

• 6 - 4 = - 10


• 6 + (- 4) = - 10


• 10 = - 10

checks

2X - 4 = - 10

add 4 to each side

2X - 4 + 4 = - 10 + 4

2X = - 6

divide each sides integers by 2

(2/2)X = - 6/2

X = - 3

------check in original equation

2(- 3) - 4 = - 10

- 6 - 4 = - 10

- 6 + (- 4) = - 10

- 10 = - 10

checks

2x -4 = -10    Add 4 to each side
2x = -6          Divide by the coefficient 2
x = -3

2x - 4 = -10
2x = -10 + 4
2x = -6
x = -6/2
x = -3

2x - 4 = -10
2x = -10 + 4
2x = -6
x = -6 / 2
x = -3
