Given the system of equations. -4x+y = 3
2x-y= 12

Which of the options represents the resulting equation after an equivalent expression for y is substituted into the second equation.

2x - (4 x + 3) = 12
-4(4 y+) + y = 3
2 (4 x+3) - y
-4 x+ 4 x-3 = 3​

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:
