Question

what is 2x+8×-5 and 23z×5=9​

Answer 1

Answer:

Simplifying

2x + 8 = 5 + -1x

Reorder the terms:

8 + 2x = 5 + -1x

Solving

8 + 2x = 5 + -1x

Solving for variable 'x'.

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

Add 'x' to each side of the equation.

8 + 2x + x = 5 + -1x + x

Combine like terms: 2x + x = 3x

8 + 3x = 5 + -1x + x

Combine like terms: -1x + x = 0

8 + 3x = 5 + 0

8 + 3x = 5

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

8 + -8 + 3x = 5 + -8

Combine like terms: 8 + -8 = 0

0 + 3x = 5 + -8

3x = 5 + -8

Combine like terms: 5 + -8 = -3

3x = -3

Divide each side by '3'.

x = -1

Simplifying

x = -1
