8x = 2 / 3 solution equation 2X of 3 = 14 of 15, 5x of 9 = 10 Within today

8x = 2 / 3 solution equation 2X of 3 = 14 of 15, 5x of 9 = 10 Within today

8x = 2 / 3 x = 1 / 12
5 of x = 7 of 10, x = 5x7 / 10 = 7 / 2
2X of 3 = 14 of 15, x = 3 / 2x14 / 15 = 7 / 5
5 / 9 x = 10 x = 9 / 5 x 10 = 18

【5x+3(10-x)=42 】 ★☆ ☆★
5x+3(10-x)=42
Find x =?
== thank you,
=

5x+30-3x=42
30+2x=42
2x=12
x=6

The solution of equation (3 Λ x) + 3 Λ 2-x = 10 is_______ .

Let a = 3 ^ X
Then 3 ^ (2-x) = 3 & # 178; △ 3 ^ a = 9 / A
a+9/a=10
Double a
a²-10a+9=0
(a-1)(a-9)=0
a=1,a=9
So 3 ^ x = 1, 3 ^ x = 9
therefore
x=0,x=2

How to solve the equation x / 10 = x-3.6?

Right x = 10x / 10 ~ last x = 4
