<h3>The solution is (x, y) = (3, -24)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x - y = 15 -------- eqn 1
y = -8x ------ eqn 2
We have to find solution of (x, y)
We can solve by substitution method
<em><u>Substitute eqn 2 in eqn 1</u></em>
-3x - (-8x) = 15
-3x + 8x = 15
5x = 15
Divide both sides by 5
<h3>x = 3</h3>
Substitute x = 3 in eqn 2
y = -8(3)
<h3>y = -24</h3>
Thus solution is (x, y) = (3, -24)
Answer:
20 maybe
Step-by-step explanation:
373-13=360
360 divided by three equal to 120
So 120 children chose basketball
The opposite on number line means is that the value of one number will be opposite to that. For example, there is number 4 on the number line, the opposite number of it will be -4. Furthermore, if there is -5 the opposite of it will be 5. Hope it help!
