Question

To draw a graph of 4 x + 5 y is equal to 19 find y when x is equal to 1

Answer 1

Answer:

Y=3

Step-by-step explanation:

• 4x+5y=19
• x=1
• 4(1)+5y=19........Put the value of x in the equation
• So: 4+5y=19
• 5y=19-4....Move 4 to RHS from LHS
• 5y=15
• y=15/5....Move 5 to RHS
• y=3

=>Therefore the value of y is 3.
