Hello there!
3x + 5 = -2
Let's start by adding - 5 to both sides
3x + 5 - 5 = -2 - 5
3x = -7
Then divide both sides by 3
3x/3 = -7/3
x = -7/3
There is one solution for this equation.
Good luck with your studies!
Answer:
x = -1
y = -2
Step-by-step explanation:
To get y by itself:
3x - y = -1
-y = -1 - 3x
y = 1 + 3x
Solve for x with substitution:
2x = 4(1 + 3x) + 6
2x = 4 + 12x + 6
2x = 10 + 12x
-10x = 10
x = -1
Plug the x value into 3x - y = -1
3(-1) - y = -1
-3 - y = -1
-y = 2
y = -2
