21/7+3/7(3x−5)=−4

Lostsunrise [7]

21/7 + 3/7(3x - 5) = -4
21/7 + 9/7x - 15/7 = -4.....multiply everything by 7
21 + 9x - 15 = - 28
9x + 6 = -28
9x = -28 - 6
9x = - 34
x = -34/9 or - 3 7/9

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (4, 1)

Point (0, 3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{3-1}{0-4}$
[Fraction] Subtract: $\displaystyle m=\frac{2}{-4}$
[Fraction] Simplify: $\displaystyle m=\frac{-1}{2}$
