Jocelyn is thinking of a number. She says that if you double the number and then take away 7 the answer will be 15. What number is Jocelyn thinking about?

What is this problem about? What does it say?

What do you think the variable should represent? Why?

Clearly define the variable.

What words in the problem can you relate to math operations (add, subtract, multiply, divide)?

Write an equation that translates this word problem into Math language.

Solve the equation.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
