Answer:
Answer is d - x = 
Step-by-step explanation:
Step 1: Add 'z' to both sides
4x -z (+z) = y + z
4x = y + z
Step 2: To solve for x, divide both sides by 4
= 
x =

Answer:
45
Step-by-step explanation:
9x10/2=45
Use the slope formula y2-y1/x2-x1
3-(-7)/1-(-1) = 10/2 = 5
To find the y-intercept:
y=5x+b
3=5(1)+b
3 = 5+b
-5 -5
-2=b
The equation of the line that passes through (-1,-7) and (1,3) is
y=5x-2
