4x+15 = 20+3x
Rearrange the constants on one side and variables on the other side.
We get,
4x-3x = 20-15
On simplifying, we get x = 5.
2x+7=10+x
Rearrange the constants on one side and variables on the other side.
We get,
2x-x = 10-7
On simplifying, we get x = 3.
2x+3 = 4+x
Rearrange the constants on one side and variables on the other side.
We get,
2x-x = 4-3
On simplifying, we get x = 1.
5x+2 = 10+4x
Rearrange the constants on one side and variables on the other side.
We get,
5x-4x = 10-2
On simplifying, we get x = 8.
