You practice playing your guitar every day. You spend 15 minutes practicing chords and the rest of the time practicing a new son
Black_prince [1.1K]

Answer:

<h2>x=(y-105)/7</h2>

Step-by-step explanation:

Given that the total time taken to practice is given by the expression as

y=7(15+x)

Simplifying the expression we have

y=105+7x

Solving for x (that is making x subject of formula we have)

7x=y-105

Divide both sides by 7 we have

x=(y-105)/7

Therefore the expression is

x=(y-105)/7

Geometry What’s the answer to 5x-6y= 33 and 2x+y = -14
V125BC [204]

Answer:

X=-3 y=-8

Step-by-step explanation:

5x - 6y = 33 \\ y  =  - 14 - 2x \\

Put the second one in first

5x - 6( - 14 - 2x) = 33 \\ 5x + 84 + 12x = 33 \\ 17x = -  51 \\ x =  - 3

y =  - 14 - 2 \times ( - 3) \\ y =  - 8
