Question:

Substitute 2x -3(x-1)=1​

Answer 1

Answer:

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

Answer 2

$\huge\sf{Answer:-}$

Given:-

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

Using distributive property

• A (B + C) = AB + AC

• A ( B - C) = AB - AC

-3(x-1) , A=(-3) , B=x and C=1

• -3x - ( - 3 ) ° 1 and - 3x + 3 ° 1

Solving

• 3 ° 1 = 3

• -3x + 3

Rewriting equation

• 2x - 3x + 3 = 1

Add and subtract elements

• 2x - 3x = - x

• - x + 3 = 1

Subtract 3 from both sides

• -x + 3 - 3 = 1 - 3

Solving

• 1 - 3 = - 2

• - x = - 2

Then, divide by -1 from both sides.

$\frac{ - x}{ - 1} = \frac{ - 1}{ - x}$

Solving

Dividing the numbers from left to right

$= (\frac{ - 1}{ - 2} =2) \\ </p><p> = (x =2)$
