For this case we must solve the following equation for x:
We apply distributive property to the terms of parentheses:
We subtract 5x on both sides of the equation:
Suamos 5 on both sides of the equation:
Answer:
Answer: (x,y) = (-10, -9)
Step-by-step explanation:
(By replacement method ...)
1- x = -2-8 it's the same thing as x = -10.
2- Replace the given value of x in equation 3x - 4y = 6
Replacing ...
3 * (-10) -4y = 6
3- Then, Multiply 3 by -10;
4) Move -30 to the right side of the equal sign, getting: 6 + 30.
-4y = 36
5) Multiply by -1
-4y * (- 1) = 36 * (- 1) is equal to 4y = -36
6) The four is multiplying the y, so pass the four <u>dividing</u>, getting:
-36/4
The ratio of -36 by 4 equals <u>-9.</u>
Therefore...
x = -10
y = -9
Answer:
2 1/10 is your answer
Step-by-step explanation:
First see how many times 20 goes into 40 which would be 2
2=whole number
since 20x2 is 40 2 is left over which will be your numerator
2 2/20 =2 1/10
