Question

seven times a number plus three times another number equals negative one. the sum of the two numbers is negative three. what are the numbers?

Answer 1

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

7(-3-y) + 3y = -1
-21 + -7y + 3y = -1
-4y = -1 + 21
-4y = 20
y = 20/-4
y = -5

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

so ur 2 numbers are : 2 and -5
