The equation 10x - 15x + 5 = -45 + 40 can be simplified to -5x + 5 = -5. By moving the numbers to one side, it becomes -5x = -10, to 5x = 10, then x = 2.

10x plus 40 is 50x.10+40=50 and then you just add the x so:10x+40=50x

Given: 15x - 20y = -1 15y = 2 + 5x Then: 15x -20(2 + 5x)/15 = -1 ∴15x -40/15 - 100x/15 = -15/15 ∴225x/15 - 100x/15 = 40/15 - 15/15 ∴125x = 25 ∴x = 1/5 Check: 15(1/5) - 20(1/5) = -1 ∴3 - 4 = -1 ∴-1 = -1

8 = 10x/(10 + x) Multiply both sides by (10 + x) to give: 8*(10+x) = 10x Simplify: 80 + 8x = 10x Subtract 8x from both sides: 80 = 2x Divide both sides by 2: 40 = x

10y plus 40 equals 50y.

Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
