Question

2x+3x=1505         ;      5x-x=4088

Answer 1

a ) \(2x+3x=1505=x\left(2+3\right)=1505=>5x=1505\)

\(=>x=301\)

b ) \(5x-x=4088=>x\left(5-1\right)=4088\)

\(=>4x=4088=>x=1022\)

Answer 2

a) 2x + 3x = 1505

x ( 2 + 3 ) = 1505

x . 5 = 1505

x = 1505 : 5

x = 301

b) 5x - x = 4088

5x - 1x = 4088

( 5 - 1 ) x = 4088

4x = 4088

x = 4088 : 4

x = 1022

Answer 3

2x+3x=1505

5x     =1505

x       =1505:5

x       =301

Vậy x=301

5x-x=4088

4x   =4088

x    =4088:4

x    =1022

Vậy x=1022

Answer 4

2x+3x =1505

5x       =1505

x         =1505:5

x         =301

5x-x= 4088

4x   = 4088

x     = 4088:4

x     = 1022
