Question

Ecuatii. 2x+1=x+3; 3x+2=2x+3; 4x-6=4-6x; 4x+6=6x+16

Answer 1

$2x + 1 = x + 3$

$2x - x = 3 - 1$

$x = 2$

$3x + 2 = 2x + 3$

$3x - 2x = 3 - 2$

$x = 1$

$4x - 6 = 4 - 6x$

$4x + 6x = 4 + 6$

$10x = 10 \: | \div 10$

$x = 1$

$4x + 6 = 6x + 16$

$4x - 6x = 16 - 6$

$- 2x = 10 \: | \div ( - 2)$

$x = - 5$
