4(x+1)=3(x+2)
4x+4=3x+6
4x-3x=6-4
X=6-4
Answer is X=2
Answer:
true
Step-by-step explanation:

* substitute 30 for x *

we're left with 15 < 20 which is true
Answer:
y=1/2-2
Step-by-step explanation:
Answer:x = 21
Explanation:In a parallelogram, each two opposite angles are equal.
In the given parallelogram ABCD, we can note that angles A and C are opposite angles. This means that they have equal measures.
Therefore:
∠A = ∠C
x + 17 = 2x - 4
17 + 4 = 2x - x
x = 21
We can check:
angle A = 21 + 17 = 38°
angle C = 2(21) - 4 = 38°
They are equal
Hope this helps :)
