Solve for x: 2+3 (x+2x) = -2x(2-4) +1

Ronch [10]

Answer:

x = -1/5

Step-by-step explanation:

2+3 (x+2x) = -2x(2-4) +1

Combine like terms

2+3(3x) = -2x (-2) +1

Distribute

2+9x = 4x +1

Subtract 4x from each side

2+9x-4x = 4x+1-4x

2+5x = 1

Subtract 2 from each sdie

5x = 1-2

5x = -1

Divide by 5

5x/5 = -1/5

x = -1/5
