Question

find out the linear equation in one variable and encircle the given equation against the serial number
I) x + 3 = 5
ii) 3y + 5 = 2
iii) 4p = 20
iv) 3y + 2x - 5z = 9​

Answer 1

Answer:

i) x + 3 = 5 is linear equation)

ii) 3y + 5 = 2 is linear equation)

ii) 4p = 20 is linear equation)

iv) 3y + 2x - 5z = 9 is not linear equation because there are three variable in this equation)

Answer 2

Answer:

1,2 and 3 are linear equation

Step-by-step explanation:

Concept

• A linear equation is an algebraic equation with an equality sign and a variable with the largest exponent of one. The equality sign (=) separates the equation into two halves, LHS and RHS.

Find

Linear equation in 4 equation

Solution

1) x+3=5 is the linear equation because only 1 variable involves

2) 3y+5=2  is the linear equation because only 1 variable involves

3) 4p=20  is the linear equation because only 1 variable involves

4) 3y+2x-5z=9 is not a linear equation because multiple variables involved
