2. Simplify:
(a) 7-9 = (-3)
(c) 5-{3 – 36 = (2 x 6-8)}
157

Step-by-step explanation:

(a) 7-9 = (-3)

Let the equation be equall to 'x'

x = 7-9 = (-3)

-2 = -3

x = -3+2 = -1

(c) 5-{3-36 = (2 x 6-8)}157

solve for answer in the parenthesis on the right hand side using bodmas

5-{3-36 =( 12-8)}157

5-{3-36 = 4}157

multiply 157 by the numbers in the bracket

5-{3x157 - 36x157 = 4x157}

5-{471 -5652 =628}

using bodmas

5-471+5652 = -628

5-6123 = -628

-6113 = -628

let y = -6113 = -628

y = -628 + 6113

y = 5485
