X=1

To solve this you start by adding like terms on the left side and doing the distributive property and adding like terms on the right. This would get you
4x+7=3x+8

Then you minus 3x on both sides getting
x+7=8

Then subtract 7 from both sides getting x=1.

7x - 3x + 7 = 3 ( x - 4 ) +20
⇔ 4x + 7 = 3x - 12 + 20
⇔ 4x - 3x = 8 - 7
⇔ x = 1

The answer would be D i think because if the two angles are to equal 72, and one of the angles equals 42, 72-42= 30. to find x, you’d do 30/6 which equals 5. so x=5 and the angle measure would be 30
