2X + (5-3x) = 15 - (7-5x) to solve the equation

2X + (5-3x) = 15 - (7-5x) to solve the equation

-x+5=8+5x
6x=5-8=-3
x=-3/6=-0.5

Solving equation: 12 + 1.5x = 1.8 + X
12+1.5X=1.8+X

1.5x-x=1.8-1.2
x=6/5

x+12=1.5x

x+12=1.5x 12=1.5X-X
12=（1.5-1）X
12=0.5X
X=24

It is known that the equation 3 [X-2 (x-a / 3)] = 4x and the equation 3x + A / 12-1-5x / 8 = 1 have the same solution. Try to find the same solution
Urgent

3 [X-2 (x-a / 3)] = 4x3x-6 (x-a / 3) = 4x3x-6x + 2A = 4x-7x = - 2aX = 2A / 7 3x + A / 12-1-5x / 8 = 1  2 (3x + a) - 3 (1-5x) = 246x + 2a-3 + 15x = 24211x = 27-2ax = (27-2a) / 21 ∵ their solutions are the same ∵ 2A / 7 = (27-2a) / 216a = 27-2aa = 27 / 8

Solve the following equation: (1) 3 (x + 5) square = 147 (2) x square - 5x-6 = 0 (3) x square + 8x + 15 = 0

3(x^2+10x+25)=147
x^2+10x+25-49=0
(x-2)(x+12)=0
X = 2 or - 12
X squared - 5x-6 = 0
(x-6)(x+1)=0
X = 6 or - 1
X square + 8x + 15 = 0
（x+5)(x+3)=0
X = - 3 or - 5

y÷（12-x）= 10,y÷（12+x）= 6
y÷（12-x）= 10,y÷（12+x）= 6

Division of two formulas: (12 + x) / (12-x) = 10 / 6
6（12+X）=10（12-X）
72+6X=120-10X
16X=48
X=3
Substitute x = 3 for y = 90

12 divided by X + 18 divided by x = 10 to solve the equation!

12 divided by X + 18 divided by x = 10 multiplied by X
12+18＝10x
10x=30
x=3

How to solve the equation (39 + x) divided by (10 + x) = 3?

(39+x)/(10+x)=3.
39+x=3(10+x).
3x-x=39-30.
2x=9
x=9/2.
