Question

ecuaciones lineales


2 (x+3) +3 (x-1) =2 (x+2)


realizar con la comprobación ​

Answer 1

$2(x + 3) + 3(x - 1) = 2(x + 2) \\ \\ 2x + 6 + 3x - 3 = 2x + 4 \\ 2x + 3x - 2x = 4 + 3 - 6 \\ 3x = 1 \\ x = \frac{1}{3} \\ x = 0.333$

comprobación

.

$2(0.333 + 3) + 3(0.333 - 1) = 2(0.333 + 2) \\ \\ 6.666 - 2.001= 4.666 \\ 4.666 = 4.666$
