Answer: X = 34
Step-by-step explanation:
Let's solve your equation step-by-step.
x+30=2x−4
Step 1: Subtract 2x from both sides.
x+30−2x=2x−4−2x
−x+30=−4
Step 2: Subtract 30 from both sides.
−x+30−30=−4−30
−x=−34
Step 3: Divide both sides by -1.
−x
−1
=
−34
−1
In this problem, we are given the equations of the two sides
of a rhombus.
Equation 1 is 4 x – 10
Equation 2 is 2 x + 20
Since the given shape is a rhombus, therefore the two sides
have equal sides. Hence, we can simply equate equation 1 and equation 2:
4 x – 10 = 2 x + 20
2 x = 30
x = 15
Therefore the answer is:
A. 15
A-All whole numbers are rational numbers
