9x + 3°
8x + 1°
find the value of x​


Sagot :

Answer:

x = 4

9(4) + 3 = 39

8(4) + 1 = 33

Step-by-step explanation:

Simplify

9x + -3 = 8x + 1

Reorder the terms:

-3 + 9x = 8x + 1

Reorder the terms:

-3 + 9x = 1 + 8x

Solving

-3 + 9x = 1 + 8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8x' to each side of the equation.

-3 + 9x + -8x = 1 + 8x + -8x

Combine like terms: 9x + -8x = 1x

-3 + 1x = 1 + 8x + -8x

Combine like terms: 8x + -8x = 0

-3 + 1x = 1 + 0

-3 + 1x = 1

Add '3' to each side of the equation.

-3 + 3 + 1x = 1 + 3

Combine like terms: -3 + 3 = 0

0 + 1x = 1 + 3

1x = 1 + 3

Combine like terms: 1 + 3 = 4

1x = 4

Divide each side by '1'.

x = 4

Simplify

x = 4
