Answer:
-8x + 16
Step-by-step explanation:
This is called expanding brackets in algebra
1. you need to multiply the numeral on outside of the brackets with each of thosse on the inside
-4 x 2x = 8x
-4 x -4 = 16
L= 4*B+42
L= the load
B is the weight of each brick
42 is the weight of the carrier
X=2
You first solve for y on the other equation 6x+3y=15 which will be: y=5-2x
Then you make it one equation: 3x-5=5-2x
Third step is add the -2x with the 3x which is will be 5x.
Fourth: your new equation will be 5x-5=5
Next u would add 5 plus which is 10
Lastly your new equation is 5x=10
I honestly hope this helps !!!!
