Yessirr
Step-by-step explanation:
Hi there!
To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.
Since
x - 4y = 5,
x = 5 + 4y
3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1
Now that we know y is -1, we can substitute it back into the equation to find x:
y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1
So, your answers are x = 1 and y = -1.
Hope this helps!
89 plus 10 is 99 so that would be the answer
Answer:
![\frac{55}{162}](https://tex.z-dn.net/?f=%5Cfrac%7B55%7D%7B162%7D)
![1\frac{1}{6}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B6%7D)
Step-by-step explanation:
![1\frac{5}{6} \div 5\frac{2}{5} = \frac{11}{6} \times \frac{5}{27} = \frac{55}{162} \\ \\ \frac{2}{3} \div \frac{4}{7} = \frac{2}{3} \times \frac{7}{4} = \frac{14}{12} = \frac{7}{6} = 1\frac{1}{6}](https://tex.z-dn.net/?f=1%5Cfrac%7B5%7D%7B6%7D%20%5Cdiv%205%5Cfrac%7B2%7D%7B5%7D%20%3D%20%5Cfrac%7B11%7D%7B6%7D%20%5Ctimes%20%20%5Cfrac%7B5%7D%7B27%7D%20%3D%20%5Cfrac%7B55%7D%7B162%7D%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B2%7D%7B3%7D%20%5Cdiv%20%5Cfrac%7B4%7D%7B7%7D%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%5Ctimes%20%5Cfrac%7B7%7D%7B4%7D%20%3D%20%5Cfrac%7B14%7D%7B12%7D%20%3D%20%5Cfrac%7B7%7D%7B6%7D%20%3D%201%5Cfrac%7B1%7D%7B6%7D)
