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)
