A.) Let x be the number of swimming lessons she had, then
402 - 15x = 237
b.) 15x = 402 - 237 = 165
x = 165/15 = 11
She had 11 swimming lessons
c.) Let the number of lesson she had be y, then 19y = 237
y = 237/19 = 12 lessons
She can pay for 12 lessons with her remaining $237.

Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.
But these things will change direction of the inequality:
Don't multiply or divide by a variable (unless you know it is always positive or always negative)
Answer:
y=3x+5
Step-by-step explanation:
Since the equation will be parallel, the slope will still be 3.
y=3x+b
Enter the point (1,8) into the equation.
8=3(1)+b
8=3+b
b=5
y=3x+5
