I need help with number 4 plz

Question

4) Insert parenthesis in each expression to make a true equation.

a) 5 - 2 x 6 - 5 + 2 = 5

b) 12/4 + 10 - 3 x 3 + 7 = 11

c) 22 - 32 - 5 x 3 - 5 = 30

d) 12 - 8 - 4 x 5 = 8

Answer 1

a (5-2)x(6-5) + 2 = 5

b 12/4 + (10-3x3) +7 = 11

the next two below aren't correct, but it's the best that comes to mind, with tiny changes in the problems

c [22+(-32-5)] x(3-5)=30

d 12-[(8-4)x5] = -8
