Question

solve i) x+9=9 ii) p+15=7 iii) 2x+1=9 iv) 4-6x=1​

Answer 1

Answer:

☆ Given- equations

☆ To find - solution of all eq.

☆ Solutions -

i) X + 9 = 9

X = 9 - 9

X = 0

ii) p + 15 = 7

p = 7 - 15

p = (-8)

iii) 2x + 1 = 9

2x = 9 - 1

2x = 8

x = 8 / 2

x = 4

iv) 4 - 6x = 1

4 - 1 = 6x

3 = 6x

3 / 6 = x

1/2 = X

Note - we can check our ans . by putting the value in the eq. for ex.

2x + 1 = 9

2( 4) + 1 = 9

8 + 1 = 9

9 = 9

hence , our ans . is right

Conclusion made from this question.

• All of these are linear equation in one variable .

• Linear equation in variable has one and only one solution .

• Graph of this equation represents a strainght line.

• As it has only one solution , line intersects at only one point in X - axis.
