Answer:
x=-50 y=35
Step-by-step explanation:
-10-3x=-4y
Insert that into the equation:
13x-4(-10-3x)=-10 so we only have 1 variable.
Use the distributive property 13x+40-12x=-10
Use the communative property: x+40=-10
Than subtract on both sides so our final solution is x=-50
Than to find out x substitute -50 for the first equation
-10-3(-50)=-4y
-10+150=-4y
140=-4y
divide so y is 35
Hope this helps!
