Question

Q3. Solve the following equation. Also verify the result. 36 - 10 ( n + 4) = 6
Q4. Solve the following equation. Also verify the result. 2( 5x - 3)-3(2x-1)= 9
​

Answer 1

Answer:

3) 36-10n-40=6

-4-10n=6

-4-6=10n

-10=10n

n=-1

verification lhs:

36-10(-1+4) = 36-10(3)= 36-30=6

lhs = rhs

4) 2(5x-3)-3(2x-1)=9

10x-6-6x+3=9

4x-3=9

4x=12

x=3

verification lhs:

2(5×3-3)-3(2×3-1)

2(15-3)-3(6-1)

2(12)-3(5)

24-15=9

lhs= rhs
