<u>System of Equations</u>
Solve the system:
x + 4y = 14
3x - 2y = 7
using the elimintation method.
To use the elimination method, we must add or subtract both equations in such a way that one of the variables goes away, and only one remains.
It requires to multiply one of them by a specific factor to match the coefficients. For example, multiply the first equation by -3:
-3x - 12y = -42
And add it to the second:
3x - 2y = 7
To result:
-14y = -35
Divide by -14:
Simplifying:
Now calculate x:

Answer:
1.874quartz
Step-by-step explanation:
Since,0.75 gallon=10cabinet
X gallon=25 cabinet
Cross multiply
10x=0.75×25
10x=18.75
Let's make x the subject of formula by dividing both sides by 10
X=1.875
So 10 cabinet=1.875quarts

Answer:
b. 5
Step-by-step explanation:
10x+18≤-12
10x≤-30
x≤-3
anything less than or equall to -3 is an option therefore it is b
