Answer:
2(x + 1) = 10
2x + 2 = 10
2x +2 -2 = 10 - 2
2x = 10(Step 3)
2x/2 = 8/2
x = 4
Step-by-step explanation:
Given the equation:
2(x + 1) = 10
Open the bracket by multiplying 2 by (x + 1) - Distributive property
2x + 2 = 10;
Subtract 2 from both sides.
2x + 2 - 2 = 10 - 2( Subtraction property of equality)
2x = 8(Step 3 justified).
Divide both sides by 2
2x/2 = 8/2 - Division property of equality.
Therefore,
x = 4. (Solved)
X=20
If they're parallel the other number in the same spot as 5x+15 equals that, so 5x+15=115 because if they are parallel they're the same if same spot and same line going through them.
115-15 = 100
5x=100
Divide by 5 both sides
X=20
If x=20 then these lines would be parallel
