How to solve:
2(5y+3)-4(7y+1)=-88
10y+6-28-4=-88
-18y=-90
y=5

Solution for Y is 5

Answer:

<h2>y = 5</h2>

Step-by-step explanation:

2(5y + 3) - 4(7y + 1) = - 88

<u>Multiply the terms in the bracket</u>

That's

10y + 6 - 28y - 4 = - 88

- 18y + 2 = - 88

<u>Subtract 2 from both sides</u>

That's

- 18y + 2 - 2 = - 88 - 2

- 18y = - 90

<u>Divide both sides by - 18</u>

\frac{ - 18y}{ - 18}  =  \frac{ - 90}{ - 18}

We have the final answer as

<h3>y = 5 </h3>

Hope this helps you

What is the solution to this system of equations?<br> y = -3x - 2<br> 6x +2y = -4
stepan [7]

Answer:

There are infinite solutions

Step-by-step explanation:

Both of these equations are the exact same. 6x+2y=-4 in y=mx+b form is y = -3x - 2. This means that since they are exactly the same, there are infinite solutions.
