Question

solve the following equation
a. 3 x -1 / 5 - x/7 = 3
b. (2x-5)/3 + (5x-4)/4=1
c.3x+5/5 - x-2/3 =5×-7/6

Answer 1

Hey friend here is your answer

a. 3 x -1 / 5 - x/7 = 3

3 x -1 / 5 - x/7 = 3
21x-21-7x/35=3
14x-21/35=3
14x-21=3×-21
14x-21=-63
14x=-63+21
14x=-42
x=-42/14
x=-3

b. (2x-5)/3 + (5x-4)/4=1

(2x-5)/3 + (5x-4)/4=1
8x-20+15x-12/12=1
23x-32/12=1
23x-32=1×12
23x-32=12
23x=12+32
23x=44
x=44/23

hope it help you ^_^
