Answer:
(2,7)
(1,-3)
(-15,-25)
Step-by-step explanation:
Because both equations are equal to the same thing (y) we can just set them equal to each other and solve for x
4x-1=2x+3
solve for x
4x=2x+4
2x=4
x=2
We know that x=2 and can plug this value in for x into any of the beginning equations
4(2)-1=y
7=y
The answer is (2,7)
2.) We can do the exact same process as question one
x-4= -3x
-4= -4x
x=1
plug this x value in into any of the starting equations
1-4=y
-3=y
The answer is (1,-3)
3.) Same deal as the other two
x-10=2x+5
-x=15
x= -15
Plug this value in for x into any beginning equation
2(-15)+5
-30+5
y= -25
(-15,-25)
