Question

Solve 7x − 10 = 4x + 8. Write a reason for each step.

hintHint:

using the additive property and subtraction property ,division property on both sides .solve for x.

The correct answer is: x = 6


    Ans:- x = 6
    Given , 7x − 10 = 4x + 8.
    Adding 10 on both sides by additive property of equality both sides remain equal.
    7x–10 + 10 = 4x + 8 + 10
    7x = 4x + 18
    Subtract 4x from both sides by subtraction property of equality both sides remains equal.
    7x - 4x = 4x + 18 - 4x
    3x = 18
    Dividing 3 left parenthesis not equal to 0 right parenthesis   by division property of equality both sides remains equal.
    fraction numerator 3 x over denominator 3 end fraction equals 18 over 3 
    ∴x = 6
