Question

Solve the equation:

10x-9 = 4(x -1) + 1

Answer 1

right side = (4x-4)+1

10x-9=4x-3
cancel -9 on the left side by adding to both sides
10x=4x+6
cancel 4x on the right side by subtracting 4x to both side
6x=6
divide and get x by itself
x=1

Answer 2

check by substituting x=1 back in

10((1)-9) = 4((1)-1)+1
1=1
