Equation: A) 4x + 2 = 3x + 5 b) (x + 5)/(2x) = 3 c) x/5+(x+3)/2 = 4

Bonsoir,

Equation:

A) 4x + 2 = 3x + 5

4x - 3x = 5 - 2

x = 3

b) (x + 5)/(2x) = 3

[tex]2x \ne 0[/tex]

[tex]x \ne 0[/tex]

x + 5 = 3 * 2x

6x - x = 5

5x = 5

x = 5/5 = 1

c) x/5+(x+3)/2 = 4

2x/10 + 5(x + 3)/10 = 4

2x + 5x + 15 = 4 * 10 = 40

7x = 40 - 15

x = 25/7
