Answer 1

$\frac{4 - 7x}{15} + \frac{1 -x }{3} = 4 - \frac{2x + 1}{5} \\ 4 - 7x + 5(1 - x) = 60 - 3(2x + 1) \\ 4 - 7x + 5 - 5x = 60 - 6x - 3 \\ - 7x - 5x + 6x = 60 - 3 + 5 + 4 \\ - 6x = 66 \\ x = - \frac{66}{6} \\ x = - 11$

Answer 2

​15​​4−7x​​+​3​​1−x​​=4−​5​​2x+1​​​4−7x+5(1−x)=60−3(2x+1)​4−7x+5−5x=60−6x−3​−7x−5x+6x=60−3+5+4​−6x=66​x=−​6​​66​​​x=−11
