Question

if -2x+3=7 and 3x+1= 5+y

Answer 1

Answer: x = -2, y = -10

Step-by-step explanation:

solve for x first in the equation -2x+3=7

-2x+3=7

-2x = 4

x = -2

now plug that x value into the other equation so we can find y

3x+1 = 5+y

3(-2)+1 = 5+y

-6+1 = 5+y

-5=5+y

-10 = y

Answer 2

Step-by-step explanation:

-2X+3=7

-2X= 7--3

X=-2

2nd equation

3(-2) +1= 5+y

y= -10
