Please help me with these questions
1. -70=7x
2. -2(x+3)
3. 6(-3w+1/3)

Answer 1

Yes I shall help you

$- 70 = 7x \\ x = - 70 \div 7 \\ x = - 10 \\ \: now \: what \: i \: did \: \\ is \: just \: changed \: to \: \\other \: side$

$= - 2(x + 3) \\ = - 2x + 6 \\ just \: multiplied$

$when \: ever \: bracket \\ is \: there \: just \\multiply$

$6( - 3w + 1 \: by \: 3 ) \\ = - 18w \: + 6 \: by \: 3 \\ = - 18w \: + 2 \: (ans)$

$last \: one \: is \\ simplification \\ sum$
