Answer: 11
Step-by-step explanation: write the equation.
2(x+4)=30
Divide by 2
x+4=15
Subtract 4
x=11
The equation of line is:

Further explanation:
Given
y = 2x + 2
Comparing it with standard form:
y=mx+b
Let m1 be the slope of given line

We know that product of slopes of two perpendicular lines is -1
Let m2 be the slope of second line

Putting the value of m2 in standard form

To find the value of b, putting (6,3) in equation

Putting the values of b and m, we get

The equation of line is:

-3p and 13p are like terms.
Hope this helps!!
AB + BC= 88
3x+ 5 + 2x+8 =88
solve for x
x= 15
