Answer:

x= 16

Step-by-step explanation:

First, you want to distribute each side! (you're gonna wanna learn this because you will be having to do it for the next 3 years no joke it sucks)

7(x+2) can be distributed as 7x+14 after multiplying 7 times x and 7 times 2, and 6(x+5) can be distributed as 6x+30.

Now, you have to get the x on one side to solve for x (so like x=__).

To do this, look at the equation as of now. 7x+14=6x+30.

We can minus 14 and bring that to the right, and minus 6x and bring that to the left to separate the x's and the regular numbers.

Now we have 16=x (or x=16).

Find the substitution 2x+3y=-5 and y=-x+5

tatuchka [14]

Answer: x = 20, y = -15

Step-by-step explanation:

Since we already know that $y=-x+5$ , we can just substitute in that value of y into the other equation:

$2x+3y=-5\\2x+3(-x+5)=-5\\2x-3x+15=-5\\-x=-5-15\\-x=-20\\x=20$

with the value of x, we can find the value of y:

$y=-x+5=-20+5=-15$

Simplify each expression using Product to a Power Property a. (9a)^2 b. ( 3x)^2

antiseptic1488 [7]

$\begin{gathered} a)81a^2 \\ b)9x^2 \end{gathered}$

1) Let's simplify those expressions making use of exponents rules:

$(9a)^2=81a^2$

Note that the exponent outside the parenthesis is 'distributed' over each term inside.

2) Similarly for the second expression we can state that:

$(3x)^2=9x^2$
