Question 25277
1.  -4+46=7(-3t+6)
-4 +46 = +42 (Since 46 is the larger number)

7(-3t+6)
In order to remove the brackets,multiply each term within the brackets with the term immediately outside the bracket
Therefore you get -21t + 42
Subtracting 42 on both sides
-21t = 0
which means t = 0

2.  -4(3b+9)=24+3(2b-8)
 -12b -36 = 24 + 6b -24
-12b -36 = 6b
Adding 12b on both sides
18b = -36
Dividing by 18 on both sides
b = -2
