Change the equation, x - y = -3, to isolate x or y and plug that new equation into the equation 2x + 3y = 4
I changed it to: x = y - 3
so
2(y - 3) + 3y = 4
2y - 6 + 3y = 4
5y - 6 = 4
5y = 4 + 6
5y = 10
y = 10/5
y = 2
then you plug that 2 into the equation x = y - 3 to get the value of x
x = (2) - 3
x = -1
you can check this by plugging the x and y values into the equation 2x + 3y = 4
2(-1) + 3(2) = 4
-2 + 6 = 4
4 = 4
hope this helps :)

The formula of a slope:
We have the points A(7, -6) and B(-4, -3). Substitute:
Answer:
b. 6
Step-by-step explanation:
I'm not 100% sure if this is the answer but here was my thinking process:
1/4 of 24 is 6, and 6 + 3 is 9, so the brothers age is probably 9, and then 24-9 is 15, and the difference between 15 and 9 is 6. Once again I don't know if this is right or not, but either way I hope this helps!
