Question

X-(7-8x) = 2
9x -(3+4x)= 4

Answer 1

X=1 for the first and x=7/5 for second. if your doing system of equations it is no solutions

Explanation:

Answer 2

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}`
