Answer:
Look at step-by-step solution
Step-by-step explanation:
2(3x-5)=6x+8
First start by dividing two from the left side:
3x-5=3x+4
From there add five and subtracted 3x from both sides:
0=9
Since zero does not equal nine, there is no solution.
Answer:
- 5 does not equal 8
Step-by-step explanation:
Distribute the 2 to get 6x - 5 = 6x +8
6x - 5 = 6x + 8
subtract 6x on both sides you are left with -5 = 8 which is not a true statment.
Since the equation leads to a statment that isn't true, there is no solution.
w - width
2w - length (l)
30 cm - perimeter
w + w + 2w + 2w = 6w - perimeter
The equation:
6w = 30 divide both sides by 6
w = 5 cm
2w = 2(5) = 10
l = 10 cm
The area of a rectangle: A = lw.
Substitute:
A = (5)(10) = 50
x-3y=-11
substitution
3x + y = 17
4x + y = 18
find for x and y
