70/85 x 100 = 82.4 (3s.f.)
5(x+1)=3x−9
Step 1: Simplify both sides of the equation.
5(x+1)=3x−9
(5)(x)+(5)(1)=3x+−9(Distribute)
5x+5=3x+−9
5x+5=3x−9
Step 2: Subtract 3x from both sides.
5x+5−3x=3x−9−3x
2x+5=−9
Step 3: Subtract 5 from both sides.
2x+5−5=−9−5
2x=−14
Step 4: Divide both sides by 2.
2x

The constant is 3.
This is because when x=1, y=3 and when x=2, y=6 so that is a constant change over each interval as seen in the graph which is 3 :)
