First attachment = 3
Second attachment = -7
Third attachment = 25
X=5. y=35.
To solve, substitute the 7x into the equation for y. Solve. You get x=5. Then put that into your first equation. Solve. You get y=35. Hope that helps!!
Answer:
(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.

(A) 0.53
Step-by-step explanation:
Number 1:
If we have the equation
, our first goal is to get rid of the x term on one side.
To do this we can subtract 3x from both sides. This leaves our equation to
. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x. This leaves
.
<em>I couldn't read Number 2 fully - I'm sorry :c</em>

Number 3:
Given the equation
, we want to isolate x on one side.
To do this, we first apply the distributive property to the left side.

Now subtract 0.6 from both sides:

And divide both sides by 3.

This rounds to 0.53.
Hope this helped!
