Find the solution of 3x-2=13.
3x-2=13
Transposing -2 to RHS, we have
Or 3x=13+2
3x=15
Or x=
(Dividing both sides by 3)
Or x=5
Solve: 5x-9=8.
5x-9=8
Transposing 9 to RHS, we have
5x=8+9=17
∴ x=
(Dividing both sides by 5)
Solve the following equation:
x-2=7
x-2=7
Transposing (-2) to RHS, we have
x=7+2
∴ x=9
Solve the following equation:
y + 3 = 10
y + 3 = 10
Transposing 3 to RHS, we have
y = 10 - 3
∴ y = 7
