25 - 4x = 15 - 3x + 10 - x
combine like terms
25 -4x = 25 -4x
add 4x to each side
25 = 5x
x= all real numbers
Answer: infinite solutions
Answer:
-4
Step-by-step explanation:
4x+3y=-1
3x + y=-7
Solve for Y
3x+y=-7
-3x. -3x
y= -3x - 7
Plug in Y into the top equation
4x + 3 (-3x - 7) = -1
Distribute the Parenthesis
4x -9x-21=-1
Combine Like terms
-5x = 20
Divide by -5 on both sides
20/-5
x = -4
I think its c hope this helps sorry if it dont
