Answer:

b = 7

Step-by-step explanation:

Given

8 - (3 + b) = b - 9 ← distribute parenthesis on the left by - 1

8 - 3 - b = b - 9, that is

5 - b = b - 9 ( subtract b from both sides )

5 - 2b = - 9 ( subtract 5 from both sides )

- 2b = - 14 ( divide both sides by - 2 )

b = 7

Can somebody number the problem and work it out for me thanks and btw it’s solving system by graphics
adoni [48]

Answer:

Solutions are (3,1) and (4,2)

Step-by-step explanation:

Graph is shown in the attached sheet

Given are two systems of equations and we have to solve them using graph

For graphing let us first prepare table for x and y.

1) y=\frac{-2x}{3} +3:\\y=2x-5

I line                                                             II line

x     0   4.5    3                              x       0      2.5     3

y      3   0       1                              y       -5      0        1

The two lines intersect at (3,1)

Hence solution is (3,1)

--------------------------------------------

2) y=\frac{x}{2} \\-6x+3y=-18

I line                                                             II line

x     0    2    4                              x       0      6     4

y      0   1      2                             y       3      0     2

The two lines intersect at (4,2)

Hence solution is (4,2)
