Question

5x+6-(x-4)=3+7(2x-1)help me please

Answer 1

Ответ:

$5x + 6 - (x - 4) = 3 + 7(2x - 1) \\ 5x + 6 - x - ( - 4) = 3 + 7(2x - 1) \\ 5x + 6 - x + 4 = 3 + 7(2x - 1) \\ 4x + 6 + 4 = 3 + 7(2x - 1) \\ 4x + 10 = 3 + 7(2x - 1) \\ 4x + 10 = 3 + 14x - 7 \\ 4x + 10 = - 4 + 14x \\ 4x + 10 - 14x = - 4 \\ - 10x + 10 = - 4 \\ - 10x = - 4 - 10 \\ - 10x = - 14 \\x = - 14 \div ( - 10) \\ x = \frac{7}{5} = 1 \frac{2}{5} = 1.4$

Answer 2

5x+6-(x4)=3+7 (2x-1)= -10х=-14=х=-14/-10=1 2/5=1.4
