Ответ:
for this case we must solve the following equation:
adding similar terms on the right side of the equation we have:
applying distributive property on the left side of the equation:
we subtract 9x from both sides:
we subtract 10 from both sides:
we divide between -4 on both sides:
x = 6
combine like terms
