Question

$4x + 6 - 7x + 9 = 18$
​

Answer 1

Answer:

4x + 6 - 7x + 9 = 18

4x-7x+6+9 = 18

-3x+15=18

-3x=18-15

-3x=3

x = 3/-3

x = -1

Answer 2

$\: \: \: \:4x + 6 - 7x + 9 = 18 \\ \\ = > 4x - 7x + 6 + 9 = 18 \\ \\ = > ( - 3x) + 15 = 18 \\ \\ = > ( - 3x) = 18 - 15 \\ \\ = > ( - 3x) = 3 \\ \\ = > x = ( - \frac{3}{3} ) \\ \\ = >\green{\boxed{ x = - 1}}$
