Question

3(x-2)+(x-1)=10

Answer 1

3 ( x - 2 ) + ( x - 1 ) = 10

3x - 6 + x - 1 = 10

4x -7 = 10

4x = 10 + 7

4x = 17

x = 17 : 4

x = \(\frac{17}{4}\)

Answer 2

\(3\left(x-2\right)+\left(x-1\right)=10\)

=> \(3x-6+x-1=10\)

=> \(\left(3x+x\right)+\left(-6-1\right)=10\)

=> \(4x-7=10\Rightarrow4x=10+7=17\)

=> \(x=\frac{17}{4}\)
