Question

What is the solution Please help

Answer 1

Answer:

Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer 2

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0  

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12:     x= $\frac{-6 + y}{2}$

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= $-\frac{-6 -6 }{2} = 6$ : x = 6
