Question

5 (x+4) = 35
5r -3 = 3r - 5
3 (x - 3) = 5 (2r + 1)​

Answer 1

Explanation:

1.5(x+4)=35

5x +20 =35

5x=35-20=15

x=15/5=3

Similarly,r=-1

Answer 2

answer:

i) 5 (x+4) = 35

5x+ 20=35

5x=35-20

5x=15

x= 15/5

x=3

ii) 5r -3= 3r-5

5r-3r= 5-3

2r=2

r=1

III) 3(x-3) = 5(2x +1)

3x-9=10x+5

10x-3x=5+9

7x=14

x=14/7

x= 2
