I don't know what you mean by equation 1. I assume you mean x + y = 7 is equation 1.

If so, solve for y as step 1.

x + y = 7

y = - x + 7

The y-intercept is 7.

Your directions do not say to solve the system of equations.

If you need to solve by graphing, use DESMOS or your graphing calculator. The solution of the system of equations is the point on the graph where the two equations meet or touch each other.

De sua jarra de suco, Claudete bebeu inicialmente 240 ml. Depois, bebeu 1/4 do que restava e, depois de algum tempo, ela bebeu o
docker41 [41]
É uma questão relativamente simples, o problema é cair em uma pegadinha do enunciado.

Se colocarmos que o jarro inicialmente tenha X ml, após Claudete beber 240 ml temos que X-240=Y. Então Claudete bebe 1/4 da jarra, por isso temos 3*Y/4=Z (Se ela bebeu 1/4, reataram 3/4). Depois, ela bebe 1/3 do volume inicial e o suco acaba, logo montamos a equação X/3=Z.

Agora temos um sistema com estas 3 equações:
--> X-240=Y
-->3Y/4=Z
-->Z=X/3

Juntando as 2 ultimas vc terá: X/3=3Y/4. E como Y=X-240.

X/3=3*(X-240)/4

Se resolver isto terá que X=432. logo a resposta é 'E'
