Answer:
solution: x = -8
Step by step:
1) 5x-5+5 = -45+5 : Add 5 to both sides
2) 5x= -40 : Simplify
3) 5x/5 = -40/5 : Divide both sides
Hope that helps
There's more than one way to combine them really
but an obvious one will be
Answer:
x = 1/2 or 0.5
Step-by-step explanation:
3x - 4 = x +5 (1) subtract x
2x - 4 = 5 (2) subtract 5
2x + 1 (3) divide by 2
x = 1/2 or 0.5
Answer:
(0,-5/2,-1)
Step-by-step explanation:
x(2x+5)(×+1)=0
x=0 2x+5=0 x+1=0
2x=-5 x=-1
x=-5/2
