How much water do I need to drink
To work out y=-5x-10 you can plot a graph.
Here is the work for that problem: 5x+ 2=12 5x= 12-2 5x=10 x= 2
the answers -20
5x+3=8 is a simple equation, and I can tell you off the top of my head the answer is 1. Here's how to work it: 5x+3=8 5x+3(-3)=8(-3) 5x=5 5x(/5)=5(/5) x=1
5x-5x = 0
2x + 5x = 357x = 35x = (35 / 7) = 5
-6 = 3 x -2 13 = 5 x 3 - 2 → 5x² + 13x - 6 = (5x - 2)(x + 3)
3/5x + 22 = 28 To solve this: Subtract 22 from both sides: 3/5x = 6 Multiply by 5x: 3 = 6*5x Divide by 6: 3/6 = 5x Divide by 5: (3/6)/5 = x Work it out: 3/6 = 0.5 0.5/5 = 0.1 x = 0.1
0
10
If: 1/3-1/5x = 15 then x work out as -3/220
