Hello!

Answer:


\Large \boxed{\sf x = 1}


\Large \boxed{\sf x = 1.4}

Explanation:

First equation:

We want to solve:


\sf x-(7-8x) = 2

◼ Simplify the left side:


\sf x-7+8x = 2


\sf9x -7 = 2

Add 7 from both sides:


\sf9x -7+7 = 2+7

Simplify both sides:


\sf 9x = 9

Divide both sides by 9:


\sf (9x)/(9) = (9)/(9)

Simplify both sides:


\boxed{\sf x = 1}

Second equation:

We want to solve:


\sf 9x -(3+4x)= 4

◼ Simplify the left side:


\sf 9x -3-4x= 4


\sf 5x -3= 4

Add 3 from both sides:


\sf5x -3+3 =4+3

Simplify both sides:


\sf 5x = 7

Divide both sides by 5:


\sf (5x)/(5) = (7)/(5)

Simplify both sides:


\boxed{\sf x=1.4}
