Question

If P = 3.8 y + 7.2 and Q = 5 y + 6. What value of "y" makes P = Q

Answer 1

Answer:

so 1 is the value of y that makes p=q

Step-by-step explanation:

$p = 3.8y + 7.2 \\ q = 5y + 6 \\ we \: have \: to \: find \: value \: of \: y \: that \: \\ make \: p = q \\ 3.8y + 7.2 = 5y + 6 \\ 7.2 - 6 = 5y - 3.8y \\ 1.2 = 1.2y \\ \frac{1.2}{1.2} = y \\ 1 =y \\ \\ lets \: check \: our \: answer \\ p = 3.8y + 7.2 \\ p = 3.8 \times 1 + 7.2 \\p = 3.8 + 7.2 \\ p = 11 \\ \\ q = 5y + 6 \\ q = 5 \times 1 + 6 \\ q = 5 + 6 \\ q = 11 \\ p = q = 11$
