Question

1. Simplifi
Simplify combining like terms:
(1) 21b - 32 + 7b - 206
(ii) - + 137" - 5z + 7z? - 157
(ii) p - (p - 9) - 9-(q-p)
(iv) 3a - 2b - ab - (a - b + ab) + 3ab + b -
(v), 5x²y - 5x + 3yx - 3y² + x² - y² + 8x7
(vi) (3y2 + 5y - 4) – (8y - y2 - 4)
​

Answer 1

Step-by-step explanation:

21b+7b-32-206

28b-238

Answer 2

Answer:

1) 21b - 32 +7b-206

21b - 7b - 206- 32 ........(rearranging)

14b - 238

Therefore, 14b = 238

Therefore, b = 238 ÷ 14 ......(238/14)

b = 17

Step-by-step explanation:

like tems can be added or substracted

after substraction taking L.H.S & R.H.S

then solving the linear equation
