7 times 7 = 49 minus 3 = 46
Answer:
Step-by-step explanation:
Given that
-3a+6b=a+4b
We want to make b subject of formula
First to remove the 4b in the Right hand side of the equation
Subtract 4b from both side of the equation
-3a+6b-4b=a+4b-4b
Then we have,
-3a+2b=a
Now to remove the -3a from the left hand side of the equation add 3a to both side
Then,
-3a+2b+3a=a+3a
2b-3a+3a=4a
Then, 2b=4a
Divide both side by 2
2b/2=4a/2
b=2a.
170 divided by 80 is 2.125, so 80 goes in 170, 2.125 times
The slope is 1 because it is parallel and y=x+b, so, 2=-3+b and b=5
y=x+5
