Need help.. too hard:(

Step-by-step explanation:

BODMAS  used.

[(3+2)*10]÷5*2=[5*10]÷5*2 (inner parenthesis)

=50÷5*2 [next parenthesis]

=10*2  {division}

=20 {multiplication}

2)

2)

3)15 - 8 + 18 ÷ 3*2 = 15 - 8 + 6*2

=15 - 8 + 12

= 7 +12

= 19

to rewrite a literal equation you may need to divide by a number, or by a variable.
