Answer:
b = -8
Step-by-step explanation:
6b = -42
Divide by 6 on both sides
b = -8
The coefficient is 2, the first number being multiplied by a variable will always be the coefficient.
( 2a + 3 ) - ( 4a - 8 ) = 7
2a + 3 - 4a + 8 = 7
-2a + 11 = 7
-2a = -4
a = -4 / -2
a = 2
You have to measure the lines with a ruler.
The Y is multiplying by 2 across the X OR the X’s are being divided by 2
Ex: 3x2=6 OR 6/3=2
