2(x + 1) = 10
2x + 2 = 10
2x +2 -2 = 10 - 2
2x = 10 (step 3)
2x/2 = 8/2
x = 4
Formula Given:
2(x + 1) = 10
2 Multiply by (x + 1) - Distribution Characteristic
2x + 2 = 10 to open the brackets.
Subtract 2 from both sides.
2x + 2 - 2 = 10 - 2 (equals subtraction property)
2x = 8 (justified in step 3).
Divide both sides by 2
2x/2 = 8/2 - property of equal division.
therefore
x = 4. (solved)
