5x - y = 6<br> -2x +y = 8<br> What’s the answer

nevsk [136]

Answer:

x= $4\frac{2}{3}$

y= $17\frac{1}{3}$

Step-by-step explanation:

$5x-y=6\\-2x+y=8\\$

Simplify, find the x-value first:

$3x=14\\x=4\frac{2}{3}$

Substitute x-value into any equation (i did the second equation) and simplify:

$-2(4\frac{2}{3})+y=8\\ -9\frac{1}{3} +y=8\\$

$y=17\frac{1}{3}$

Rosa wrote down a fraction on a piece of paper. If you take her fraction and multiply it by eight you get eleven. can you guess

Leviafan [203]

Well 8 times 1.375 equals 11, so we just have to convert 1.375 into a fraction. That means her fraction is $\frac{11}{8}$ , or 1 $\frac{3}{8}$ , depending on what kind of fraction she wants.
