Dont spam!!Ml aggarwal class 6th!! ​

Answer 1

Step-by-step explanation:

a 3x + 13 = 15- x

3x + x = 15-13

4x =2

x =1/2

b 3(X+6) +2(X+3)=64

3x+18+2x+6=64

5x+24=64

5x =64-24

5x =40

X =8

c 3x/15=15

3x = 15×15

3x = 225

X=75

d x/5-7=1

x-35/5=1

x-35=5

X =40

Answer 2

3x + 13 = 15 - x

3x + x = 15 - 13

4x = 2

x = 2/4

x = 1/2

3(x + 6) + 2(x + 3) = 64

3x + 18 + 2x + 6 = 64

5x + 24 = 64

5x = 64 - 24

5x = 40

x = 8

3x/15 = 15

3x = 15 x 15

3x = 225

x = 225/3

x = 75

x/5 - 7 = 1

x/5 - 35/5 =1

(x - 35)/5 = 1

x - 35 = 1 × 5

x - 35 = 5

x = 5 + 35

x = 40
