Answer:
x = 1, y = -4
Step-by-step explanation:
set each equation equal:
-7x + 3 = -x - 3
-6x + 3 = -3
-6x = -6
x = 1
y = -7 + 3
y = -4
To start we need to put all the b's on the same side.
4b + 6 = 2 - b + 4
To move the b on the right side to the left side, add b to both sides.
4b + 6 + b = 2 - b + 4 + b
Simplify. 4b + b = 5b and -b + b = 0 so...
The equation is now: 5b + 6 = 2 + 4
Now move 6 to the right side so we can isolate b.
5b + 6 - 6 = 2 + 4 - 6
Simplify.
5b = 0
Solve for b.
b = 0/5
b = 0
