The first thing you do is subtract 2 from both sides to move the 2 to the left side
3-6x=7x
now add 6x to both sides to move -6x to the right
3=13x
divide by 13 to eliminate the 13 on the right side
3/13
Good morning Brainiac
x+y = 13
1/2 x +y = 10
We gonna solve x+y=13 for x
So let's start by adding -y to both sides
x+y -y = 13-y
x= -y +13
Now substitute -y+13 for x in 1/2 x +y=10
1/2 x +y = 10
1/2 (-y+13)+y=10
1/2 y + 13/2 = 10
Now add -13/2 to both sides
1/2 y+13/2 -13/2 = 10- 13/2
1/2 y = 7/2
Now eliminate the common denominator which is 2
y = 7
Now we have the value for y, so lets find the value for x by substitute 7 for y in x= -y+13
x= -y+13
x= -7 + 13
x= 6
Answer : (6,7)
The answer is B
I hope that's help and if you have questions please let me know :)
Good luck
Parallelogram area= base * perpendicular height
Assuming that the perpendicular height is 2 ft:
Area of one window = 3.25 * 2 = 6.50 square feet.
Since there are 3 identical parallelograms the Total Area = 3 * 6.5
= 19.5 square feet.
Answer:
In this equation, the value of x is 9.
Step-by-step explanation:
-4(6x + 3) = -12(x + 10)
Distribute -4 to (6x + 3) and distribute -12 to (x + 10).
-24x - 12 = -12x - 120
Add 12x on both sides of the equation.
-12x - 12 = -120
Add 12 on both sides of the equation.
-12x = -108
Divide -12 on both sides of the equation.
x = 9
The value of x in this equation is 9.
