Question

(2xx-3)x3-5=10

Answer 1

\(\left(2\cdot x-3\right)\cdot3-5=10\)

\(\left(2x-3\right)\cdot3=15\)

\(2x-3=5\)

\(2x=8\)

\(x=4\)

Answer 2

\(\left(2\times x-3\right):3-5=10\)

\(\left(2\times x-3\right)\times3=10+5\)

\(\left(2\times x-3\right)\times3=15\)

\(2\times x-3=15:3\)

\(2\times x-3=5\)

\(2\times x=5-3\)

\(2\times x=2\)

\(x=2:2\)

\(x=1\)

Answer 3

(2xx-3)x3-5=10

(2xx-3)x3=10+5=15

(2xx-3)=15:3=5

2xx=5+3=8

2xx=8

xx=8:2=4

x=2

Vậy x=2

Answer 4

\(\left(2×x-3\right)×3-5=10\)

\(\left(2×x-3\right)×3=10+5=15\)

\(2×x-3=15:3=5\)

\(2×x=5+3=8\)

\(x=8:2=4\)

Answer 5

( 2 x x - 3 ) x 3 - 5 = 10

2 x x = { 10 + 5 } : 3 + 3

2 x x = 8 

=> x = 8 : 2 

=> x = 4

Answer 6

(2·x−3)·3−5=10

(2x−3)·3=15

2x−3=5

2x=8

x=4

Answer 7

\(\left(2.x-2\right).3-5=10\)

\(\left(2x-3\right).3=15\)

\(2x-3=5\)

\(2x=8\)

\(x=4\)
