4x-3 is the answer. Hope this helps:)
Answer:
14x+3=8x+3
14x+3 -3 = 8x+3 -3
Cancels out the 3
14x = 8x
14x - 8x = 8x -8x
Cancels out the 8x
14x = 0
x = 0
Step-by-step explanation:
Answer:
<h2>x = 6, y = 42</h2>
Step-by-step explanation:
The diagonal divides both opposite angles into two angles. If ABCD is a parallelogram, then opposite sides are parallel, so we have alternate exterior angles.
Alternate exterior angles are congruent.
Therefore we have the equations:
4x = 24 and y - 10 = 32
4x = 24 <em>divide both sides by 4</em>
4x/4 = 24/4
x = 6
y - 10 = 32 <em>add 10 to both sides</em>
y - 10 + 10 = 32 + 10
y = 42
Answer:
The second option.
3x + 6 = 21.
Step-by-step explanation:
3x + 6 = 21.
If x = 5, plug it in.
3 · 5 + 6 = 21
15 + 6 = 21
Hope this helps,
