<h3><u>The value of x is equal to -4.076</u></h3><h3><u>The value of y is equal to 5.057</u></h3>
3x + 4y = 8
7x - 8y = -69
<em><u>To make this easier, we can multiply each term in the first equation by 2.</u></em>
6x + 8y = 16
Now, we can use elimination to isolate one variable.
<em><u>Combine equations.</u></em>
13x = -53
<em><u>Divide both sides by 13.</u></em>
x = -4.076
We can plug this value of x into the equation to find the value of y.
3(-4.076) + 4y = 8
-12.228 + 4y = 8
<em><u>Add 12.228 to both sides.</u></em>
<em><u>4y = 20.228</u></em>
Divide both sides by 4.
y = 5.057
Answer:
No
Step-by-step explanation:
She is not right. You must simplify 3² first.
In the Order of Operations, exponents come before division.
X = 3 I believe is the answer
Answer:
Step-by-step explanation:
3x - 5y = -35
2x - 5y = -30
3x - 5y = -35
-2x + 5y = 30
x = -5
3(-5) -5y = -35
-15 - 5y = -35
-5y = -20
y = 4
