Show the result of substituting x=0 into 0.75x+1.5y=40

prohojiy [21]

Answer:

y=26.67

Step-by-step explanation:

The given equation is 0.75x+1.5y=40.

We need to show the result of substituting x=0 in above equation.

0.75x+1.5y=40

Put x = 0

0.75(0)+1.5y=40

0+1.5y=40

⇒ 1.5y=4

$y=\dfrac{40}{1.5}\\\\y=26.67$

So, the value of y = 26.67 when x = 0.
