2x + 22 = 4(x + 3)<br> Please help me
Annette [7]

Answer: x=5

Step-by-step explanation:

2x+22=4(x+3)

First distribute

2x+22=4x+12

Now intractable 2x from both sides

22=2x+12

Now subtract 12 from both sides

10=2x

Now divide by 2 to get x alone

5=x

So

x=5

Easy question, easy points
Juli2301 [7.4K]

Answer:

Step-by-step explanation:

The solution of a system of linear equations is the point of intersection of their graphs because the intersection represents the only x or y values that will satisfy both/all equations. The graph visually shows that the intersection of these equations is the only spot on the graph that all of the equations have in common. This means that only this spot will satisfy all equations. For example, the intersection may be (0,1); this means that for all equations an x value of 0 will always result in the y value of 1. However, an x or y value that satisfies one equation may not satisfy the others if they do not lead to the desired outcome.

Eight times the sum of 9 and some number is 192.​
vovikov84 [41]

Answer:

15

Step-by-step explanation:

To solve this, divide 192 by 8:

192/9 = 24

Subtract 9 from 24:

24 - 9 = 15

Therefore, 8 times the sum of 9 and 15 is 192
