Answer:
(-2, -4.5)
Step-by-step explanation:
We can solve this equation with substitution.
x=2y+7
3x-2y=3
We can "substitute" 2y+7 for x into the second equation:
3(2y+7)-2y=3
Distribute the 3
6y+21-2y=3
Add like terms
4y+21=3
Subtract 21 from both sides
4y=-18
Divide both sides by 4 to isolate y
y=-4.5
Plug -4.5 back in for y:
x=2(-4.5)+7
x=-9+7
x=-2
(x,y)=(-2,-4.5)
- 6+ 5x = 6x - 3
move -6 to the other side
sign changes from -6 to +6
-6+6+5x= 6x-3+6
5x= 6x-3+6
5x= 6x+3
move -6x to the other side
sign changes from +6x to -6x
5x-6x= 6x-6x+3
5x-6x= 3
-x= 3
mutiply both sides by -1 to get +x
(-1)(-x)= x , (-1)(3)= -3
Answer: x= -3
