What is the answer to this equation using substitution x+y=1

FromTheMoon [43]

{ x + y = 1 * ( - 2 )
2 x + 3y = -4

- 2 x - 2 y = - 2
2 x + 3 y = - 4
_______________
y = - 6

Subsititute y = - 6
<span>
2 x + 3 y = - 4

2 x + 3 * (-6) = -4

2 x - 18 = - 4

2 x = - 4 + 18

2 x = 14

x = 14 / 2

x = 7

The solution to the system of equations are:

x = 7 and y = - 6

Graph the line with 3/4 slope<br> passing through the point (2,-2).

S_A_V [24]

Answer:

Step-by-step explanation

x1 = 2, y1 = -2 and m = 3/4

y - y1 = m(x - x1)

y - (-2) = 3/4(x - 2)

y + 2 = 3/4(x - 2)

Multiply each term by 4

4y + 8 = 3(x - 2)

4y + 8 = 3x - 6

4y = 3x - 6 - 8

4y = 3x - 14
