Answer:
x = 3 x = ‐1/4
Step-by-step explanation:
Was right on the quiz
h=4 because 4+6=10 and 10/5=2
A) 42x-12
6*7=42. 6*2=12
b) 21y
11+4+6=21
Answer:
x = 4
Step-by-step explanation:
<u>We are given the equations: </u>
10x = 10
-5x - 8y = 9
Since we don't have a coefficient of y in the first equation, we will rewrite the first equation as:
10x + 0y = 10
<u>Writing an Augmented matrix for the 2 equations:</u>
10x + 0y = 10
-5x - 8y = 9
