Well in order to solve this we need to get the solution to each side. 

(23+) +19 = 23 + ( +19) 
23 + 19        23 + 19 
   = 42            = 42 

So this means 
each side equals 42 

42 = 42 

So this means there are infinite solutions 

Good Luck! :)

1)B -26-27x
steps :distribute ,-9 times 3 =-27 , -9 times 3x = -27x , now combine like terms :you have a 1 and a -27 ,1-27=-26,and you left with -27



2)D 11-49x
steps :distribute , positive 7 times 1= 7 and then positive 7 times negative 7x =-49, now combine like terms ,since you have a positive 4 combine it with positive 7 which is 11 and finally put it together with -49x which it would look like 11-49x

One integer is 7 more than another. Their product is 98. Find the integers,
ipn [44]

Answer:

- 14, - 7 or 7, 14

Step-by-step explanation:

Let the the two integers be x and (x + 7)

\therefore \: x(x + 7) = 98 \\  {x}^{2}  + 7x - 98 = 0 \\  {x}^{2}  + 14x - 7x - 98 = 0 \\ x(x + 14) - 7(x + 14) = 0 \\ (x + 14)(x - 7)  = 0 \\ (x + 14) = 0 \: or \: (x - 7) = 0 \\ x =  - 14 \: or \: x = 7 \\  \\ when \: x =  - 14 \\ x + 7 =  - 14 + 7 =  - 7 \\  \\ when \: x = 7 \\ x + 7 = 7 + 7 = 14 \\

Hence the required integers are - 14, - 7 or 7, 14

In the figure, AC = BC. Find the value of b. ​
bazaltina [42]

Since AC = BC, we can say that this triangle is isoceles (at C)

In an isoceles triangle, the two angles that does not belong to the top angle (which in this case is C) is equal to each other.

Now, we can find the sum of the 2 missing angles : 180 - 52 = 128.
And since they are equal, we can find b : 128 : 2 = 64/
