Question

• find three solution of equation x=3y-5.
• write 2x=3y-6 in standard form and fund the value of a,b,c.
​

Answer 1

Answer:

Express each of the following equations in the form ax + by + c = 0 and indicate the values of a, b, c in each case.

(i) 3x + 5y = 7.5

(ii) 2x−y5+6=0

(iii) 3y – 2x = 6

(iv) 4x = 5y

(v) x5−y6=1

(vi) 2–√x+3–√y=5

ANSWER:

(i) 3x + 5y = 7.5

This can be expressed in the form ax + by + c = 0 as 3x+5y+(−7.5)=0.

(ii) 2x−y5+6=0

This can be expressed in the form ax + by + c = 0 as 2x+(−15)y+6=0

(iii) 3y – 2x = 6

This can be expressed in the form ax + by + c = 0 as 2x+(−3y)+6=0.

(iv) 4x = 5y

This can be expressed in the form ax + by + c = 0 as 4x−5y+0=0

(v) x5−y6=1

This can be expressed in the form ax + by + c = 0 as 6x−5y=30

(vi) 2–√x+3–√y=5

This can be expressed in the form ax + by + c = 0 as
