Question

3. Solve the following equations by systematic method:
$(i) \frac{3y}{5} - 6 = 3 (ii)3(m + 4) + 5 = 26 (iii) - 4(2 - y) = 16(iv) \frac{2m}{5} - 3 = 7$
​

Answer 1

Answer:

(i) 3y/5-6=3.

3y-6=3×5.

3y-6=15.

3y=15+6.

3y=21.

y=21/3.

y=7.

(ii) 3(m+4)+5=26.

3m+12+5=26.

3m=26-12-5.

3m=14-5. (Because +×-=- & largest number is important).

3m=9.

m=9/3.

m=3.

(iii) 4(2-y)=16.

8-4y=16.

4y=16+8.

4y=24.

y=24/4.

y=6.

(iv) 2m/5-3=7.

2m-3=7×5.

2m-3=35.

2m=35+3.

2m=38.

m=38/2.

m=19.

I think this is your answer.
