2x + y = 0
Y = x + 3
I have to solve this with substitution method, help .

First you’re going to use Y and add it in so your equation will be. 2x + x + 3= 0 then youre going to add like terms. so 2x + x = 3x next you’re going to take out the three. since it’s positive we’re going to subtract it. so now you’ll have 3x = -3 next we’re going to isolate the variable. divide the -3 by your 3x which will = -1 since there was a negative. so your answer is -1

What the heck don’t understand
