To find the solution, we use the substitution method.
x+y=-1
<span>x-3y=11
</span>
x+y = -1-y
-y
x = -1-y
Now apply the value of x into the other equation.
x-3y=11
-1-y-3y = 11
Combine like terms
-4y -1 = 11
+1 +1
-4y = 12
-4y = 12
-4y/-4 = 12/-4
y = -3
Now, apply the value of Y to one equation to find x.
y = -3
x -3 = -1
+3 +3
x= 2
Now we have the value for both, x and y.
x = 2
y =-3
Final answer: A. <span>(2, −3)</span>
Answer:
x= 35/11
Step-by-step explanation:
steps
35 = 11x
swich sides
11x = 35
Divide both sides by 11
11x/11 = 35/11
simplify
x = 35/11

Answer:
Prove what is similar?????
<em>The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
</em>
<em>
</em>
<em>Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
</em>
<em>
E=17/20(1)</em>
<em>E=1/20=0.85</em>
<em>0.85 Euros have the same amount as 1 U.S dollar.
