Answer:
X=-1, y=4
Step-by-step explanation:
by using eliminating property
by substitution
X=-1
B-(-7)= -1
First negative multiply by negative is POSITIVE.
So: B+7= -1
Subtract 7 from both sides
B= -7-1
B= -8.
Answer: -8.
To Check Answer: Plug in the variable of B in the original equation.
So: -8-(-7)= -1
-8+7= -1
-1= -1
If the Solution works out the answer is right.

Answer:
-3 is not a solution
Step-by-step explanation:
Subtstitute the possible solution into the equation and see if it is true
3x -5 = 4+2x
3(-3) -5 = 4+2(-3)
-9-5 = 4-6
-14 = -2
This is not true so -3 is not a solution
