Solve the system by substitution.<br> -6y = x<br> x +y = -30

Komok [63]

Answer:

$- 6y = x \\ \\ y = - \frac{x}{6} \\ \\ \\ x + y = - 30 \\ x + ( - \frac{x}{6} ) = - 30 \\ \\ x - \frac{x}{6} = - 30 \\ \\ \frac{6x}{6} - \frac{x}{6} = - 30 \\ \\ \frac{6x - x}{6} = - 30 \\ \\ \frac{5x}{6} = - 30 \\ \\ 5x = - 30 \times (6) \\ \\ 5x = - 180 \\ \\ x = - \frac{180}{5} \\ \\ x = - 36 \\ \\ \\ \\ y = - \frac{x}{6} \\ \\ y = - \frac{( - 36)}{6} \\ \\ y = \frac{36}{6} = 6 \\ \\ y = 6 \\ \\ ( - 36 \: , \: 6)$

X+y=4 and 2x+3y=2 then find x and y

Sladkaya [172]

Answer:

x=10, y=-6

Step-by-step explanation:

1) express x from the first equation x+y=4 x=4-y

2) It is the system of equations, so both equations are simultaneous.

you can replace x to 4-y in the second one

2 *(4-y) +3y=2

8-2y+3y= 2

y=-6

x= 4-y=4-(-6)=10

The answer is x=10, y=-6
