Question

A wire is (y-5) metre long. Another wire is (3y-2) metres long. If both the wires are joined, find the total length of joined wire. *

Answer 1

Answer:

(y - 5) + (3y - 2) = 0

y - 5 +3y - 2 = 0

4y - 7 = 0

4y = 7

y = 7/4

y= 1.75m

therefore, the total length of the wires is 1.75 meter

Answer 2

Answer:

4y-7 m

Step-by-step explanation:

equation : (y-5)+(3y-2)

solve:

(y-5)+(3y-2)

or y-5+3y-2

or y+3y-5-2

or 4y-7m
