Solve the equation: 15+ 5x = -x - 3

x = -3

Step-by-step explanation:

to solve the equation we will collect the like terms and evaluate

15 + 5x = -x-3

15 + 5x + x = -3

15 + 6x = -3

6x = -3 - 15

6x = -18

divide both side by  the coefficient of x which is 6

6x/6 = -18/6

x = -3

to check if your answer is correct we will  put the value of x = -3 into the  equation and we will  check if the right handside equals to the left handside.

15 + 6x = -3

15 + 6(-3) = -3

15 - 18 = -3

-3 = -3 proved

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?

your answer is the frist one
