Please help i cant figure these out!!!!
Show work

1. solve for x and y

3x+1=y 2y-5=5x

2. solve for x and y

x+1=y 2x=3y-7

3.solve for x and y

x=y+2 y+10=2x-8

Respuesta :

1.
5x+2(3x+8)=5 3(-1)+1= y. y=-2
5x+6x+16=5
11x+16=5
11x= -11
x= -1
(-1,-2)
2.
2x= 3(x+1) -7 4+1=y. y= 5
2x=3x+3-7
2x=3x-4
-1x=-4
x= 4
(4,5)
3.
y+10= 2(y+2)-8. x= 14+2. x=16
y+10= 2y +4 -8
y+10= 2y -4
10=1y -4
14= y
(16,14)

Answer:

1. y = 5/2x +5/2

x = 2/5y -1

2. y = 7/3 + 2/3x

x = 3/2y - 7/2

3. (x,y) = (8, -2/3)
