Answer:
x=5
Explanation:
alternate angles (I.e. z angles)are equal
:. 7x+25=60
collecting like terms
7x=60-25
7x=35
divide both sides by the coefficient of x
7x/7=35/7
7 cancels out
x = 5
60=7x+25 - Starting equation
Take 25 and subtract it so you leave your x and equal value
35 = 7x
Divide so you can find your x
5 = x
