2.5 (x + 2) - 4.5 (X-6) = 5x-7, how to solve x

2.5 (x + 2) - 4.5 (X-6) = 5x-7, how to solve x


The original formula is - 2x + 5 + 27 = 5x-7, 7x = 39, x = 39 / 7



If 4.5X = 7 / 2, x = ()
63b63 / A4, 4C9 / A4, 7d7 / A4


c



x-7/4-5x+8/2=1
(x-7)/4-(5x+8)/2=1


X-7 / 4-5x + 8 / 2 = 1 x-1.75-5x + 4 = 15x-x = 4-1-1.754x = 1.25x = 1.25 / 4x = 0.3125 (X-7) / 4 - (5x + 8) / 2 = 12 (X-7) - 4 (5x + 8) = 8 (multiply both sides of the equation by 8) 2x-14-20x-32 = 82x-20x = 8 + 14 + 32-18x = 54x = 54 / (- 18) x = - 3



How to solve x + 5.5x = 13?


x*1+5.5x=13
x*(1+5.5)=13
x*6.5=13
x=13/6.5
x=2
The solution is absolutely correct. The "*" means multiplication and the / "means division
