Question
Solve 3(5x + 1) = 2(x + 21). Write a reason for each step.
Hint:
using the additive property and subtraction property ,division property on both sides .solve for x.
The correct answer is: x = 3
Ans:- x = 3
Given ,3(5x + 1) = 2(x + 21).
By left distributive property 15x + 3 = 2x + 42
Subtract 2x from both sides by subtraction property of equality both sides remains equal.
15x - 2x + 3 = 2x + 42 - 2x
13x + 3 = 42
Subtract 3 from both sides by subtraction property of equality both sides remains equal.
13x + 3 - 3 = 42 - 3
13x = 39
Dividing 9
by division property of equality both sides remains equal.
x = 3
