X= 51 is the answer you need to remember that since they share a straight line you add the together to get 180 which is half a circle

Answer:

x = 51

Explanation:

The two angles form a straight line

Angles that form a straight line add up to equal 180

Hence, 2x + 4 + x + 23 = 180

( note that we just created an equation that we can use to solve for x )

we now solve for x using the equation we created

2x + 4 + x + 23 = 180

step 1 combine like terms

2x + x = 3x

4 + 23 = 27

we now have 180 = 27 + 3x

step 2 subtract 27 from each side

180 - 27 = 153

27 - 27 cancels out

we now have 153 = 3x

step 3 divide each side by 3

153 / 3 = 51

3x / 3 = x

we're left with x = 51
