-8 + b = 4 add 8 to both sides: b = 12

b = 12 12(3)+3 = 39, use a calculator to find out

b=12

1.5

5b = 8 therefore b = 8/5 therefore b = 1.6

Addition is commutative. That is, a + b = b + a for all a, b

-8 + b = 4 add 8 to both sides: b = 12

3b+4 = b+12 3b-b = 12-4 2b = 8 b = 4

B=61

in order to solve this problem you have to solve for x first wich you are given the data to pre forme so x=4 and x.2=8 and 8=y and y-4=4=a=x so a+8=12 and 12=b

b = 12 12(3)+3 = 39, use a calculator to find out

12 = -4/2 * -2 + b 12 = -2 * -2 + b 12 = 4 + b 8 = b

5b = 8 b = 8/5 or 1.6

b=12

12 = -4/7 * -2 + b 12 = 8/7 + b 10 6/7 = b

Evaluate -4(a+b) - 10a/b when a=8 and b=5
