Question

ache o valor da equação 4 x + 2 + 18​

Answer 1

Resposta:

Simplifying

0.4(x + -2) = 18

Reorder the terms:

0.4(-2 + x) = 18

(-2 * 0.4 + x * 0.4) = 18

(-0.8 + 0.4x) = 18

Solving

-0.8 + 0.4x = 18

Solving for variable 'x'.

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

Add '0.8' to each side of the equation.

-0.8 + 0.8 + 0.4x = 18 + 0.8

Combine like terms: -0.8 + 0.8 = 0.0

0.0 + 0.4x = 18 + 0.8

0.4x = 18 + 0.8

Combine like terms: 18 + 0.8 = 18.8

0.4x = 18.8

Divide each side by '0.4'.

x = 47

Simplifying

x = 47
