Answer 1

Answer:

(7)

=9x-4=3(x-4)

=9x-4=3x-12

=9x+3x=4-12

=12x=8

=x=8/12

= factor of 8 and 12

=x=4×2/4×3

=4 and 4 will cut

=x=2/3

(9)

=5x-3=3x+7

=5x-3x=3+7

=2x=10

=x=10/2

=x=5

(11)

=5x-2=3x+104

=5x-3x=2-104

=2x=102

=x=51

(13)15+6x=4x+3

=6x-4x=15+3

=2x=18

=x=18/2

=x=9

(15)

=12x-4=6x-9

=12x-6x=9-4

=6x=5

=x=6/5

(17)

=9x-4-3x-12=4x-4

=9x+3x-4x=12+4-4

=8x=12

=x=12/8

=you have to do factor of 8 and 12

=x=4×2/4×3

=you have to cut 4 and 4

=x=2/3

Answer 2

Step-by-step explanation:

given equation is 8x – 3/ 3x=2 —-(1)

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x8x – 6x = 3

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x8x – 6x = 32x = 3

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x8x – 6x = 32x = 3x = 3/2

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x8x – 6x = 32x = 3x = 3/2We can check by substituting the value of x in the above equation (1)

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x8x – 6x = 32x = 3x = 3/2We can check by substituting the value of x in the above equation (1)8 × 3/2 – 3 /3 × 3/2

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x8x – 6x = 32x = 3x = 3/2We can check by substituting the value of x in the above equation (1)8 × 3/2 – 3 /3 × 3/224-6/2 / 9/2 = 2

given equation is 8x – 3/ 3x=2 —-(1)8 x-3 = 2 × 3x. We have to solve the equation by finding x.8x-3 = 6x8x – 6x = 32x = 3x = 3/2We can check by substituting the value of x in the above equation (1)8 × 3/2 – 3 /3 × 3/224-6/2 / 9/2 = 2Hence RHS =LHS, verified
