Question

solve this system of linear equations separate the x and y values with a comma -14x=-7-7y -10x=-15-7y

Answer 1

-14x = -7 - 7y
-10x = -15 - 7y...multiply by -1
---------------
-14x = -7 - 7y
10x = 15 + 7y (result of multiplying by -1)
-------------add
-4x = 8
x = -8/4
x = -2

-10x = -15 - 7y
-10(-2) = -15 - 7y
20 = -15 - 7y
20 + 15 = -7y
35 = -7y
-35/7 = y
-5 = y

solution is (-2,-5)

Answer 2

X=7/4+7/4y ,y∈ (One symbol I can't find but that's what I got)
