Question

Does anyone know this ? kinda confused because I have learned this yet I think

Answer 1

Answer:

a. 0

b. 0 (undefined)

c. 14

d. 0 (undefined)

Step-by-step explanation:

a. Make x on its own

x = 5 - 5

x = 0

b. Collect like terms (terms that have same variable)

2x - 6 = 2x - 6

Rearrange equation

2x - 2x = -6 + 6

0x = 0

x = 0 (undefined) -- This is because when you divide something by 0 (when 0 is the denominator), it is undefined

c. Rearrange to make whole numbers on one side

3x = 43 - 1

3x = 42

Divide both sides by 3 to make x on its own

x = 14

d. 4x - 4x = 7 + 1

0x = 8

x = 0 (undefined)
