Question

2x+3y+1 para x=2/3 e y=-1/2

Answer 1

$\mathsf{2x+3y+1}\\\\\\ \mathsf{x=\dfrac{2}{3}}\\\\ \mathsf{y=-\dfrac{1}{2}}\\\\\\\\ \mathsf{2x+3y+1=2\cdot\dfrac{2}{3}+3\cdot-\dfrac{1}{2}+1}\\\\\\ \mathsf{2x+3y+1=\dfrac{4}{3}-\dfrac{3}{2}+1}\\\\\\ \mathsf{2x+3y+1=\dfrac{4}{3}-\dfrac{3+2}{2}}\\\\\\ \mathsf{2x+3y+1=\dfrac{4}{3}-\dfrac{1}{2}}\\\\\\ \mathsf{2x+3y+1=\dfrac{8}{6}-\dfrac{3}{6}}\\\\\\ \boxed{\mathsf{2x+3y+1=\dfrac{5}{6}}}$

Answer 2

Olá, boa noite ☺

Resolução:

2x + 3y + 1.

2.(2/3) + 3.(-1/2) + 1.

4/3 - 3/2 + 1.
