two-thirds:  \frac{2}{3} \\ number: b \\ plus: + (add) \\ 4: 4 \\ is: equal (to) \\ 7:7 \\ \\ \\ \\ Problem:  \frac{2b}{3} + 4 = 7

Finding our answer (if we had to solve it as well)↓

\frac{2}{3}b + 4  - 4 \\ 7 - 4 = 3

\frac{2}{3}b = 3

\frac{3}{2} ( \frac{2}{3}) (← cancel this out because that would give you a 1 by itself \frac{3}{2} (3) =  \frac{9}{2}

Answer: B =  \frac{9}{2}

2/3x + 4 = 7
         -4    -4
4 cancels out.
2/3x = 3
x 3      x3
6/3 = 2x = 9
         /2     /2
2 cancels out.
x = 9/2 = 4.5

X= 7 4. Find the equation of a line passing through (5, -6) perpendicular (b) 3x + 5y = (d) 7x - 12y (f) x = 7 (a) 2x + y = 12 (
goldfiish [28.3K]

Given data:

The first set of equations are x+y=4, and x=6.

The second set of equations are 3x-y=12 and y=-6.

The point of intersection of first set of te equations is,

6+y=4

y=-2

The first point is (6, -2).

The point of intersection of second set of te equations is,

3x-(-6)=12

3x+6=12

3x=6

x=2

The second point is (2, -6).

The equation of the line passing through (6, -2) and (2, -6) is,

\begin{gathered} y-(-2)=\frac{-6-(-2)}{2-6}(x-6) \\ y+2=\frac{-6+2}{-4}(x-6) \\ y+2=x-6 \\ y=x-8 \end{gathered}

Thus, the required equation of the line is y=x-8.
