Algebra always makes things sound harder than they actually are, and weird vocabulary can mix up the steps we knew so well.
Part 1: Multiply the first equation by a 2 so that you can cancel out the y variable.
6x - 2y = 0
5x + 2y = 22
Part 2: Actually cancel out the y variables, and combine like terms.
11x = 22
Part 3: Solve for "x" by dividing both sides by 11
x = 2
Part 4: Substitute the variable "x" with the value we just solved for in the original equation.
3(2) - y = 0
6 - y = 0
Then, solve for y by adding y to both sides
6=y
Solution Set = {2,6}
15)
an exterior angle equals the sum of the remote interior angles
<span>so
m<XYT = m<X + m<Z
4x - 25 = x + 15 + 50 - 3x
4x - 25 = -2x + 65
6x = 90
x = 15
answer
x = 15

0.78 ÷ 106 = 39/5300
= 0.007358490566037
Explanation: Convert 0.78 into a fraction
0.78 = 39/50. Next you do, 39/50 ÷ 106.
Answer: Creo que no
Step-by-step explanation:
un numero entero es un numero negativo como:
-4
-0.87
-979.27
N=1/2/18
n=1/2 multiplied 1/18
n=1/36
