If you would like to solve the system of equations, you can do this using the following steps:

-3x + 4y = 12
x * 1/4 - 1/3 * y = 1 ... x * 1/4 = 1 + 1/3 * y ... x = 4 + 4/3 * y
_____________
<span>-3x + 4y = 12
</span>-3 * (4 + 4/3 * y) + 4y = 12
-12 - 4y + 4y = 12
-12 = 12
-12 - 12 = 0
-24 = 0

The correct result would be: <span>the system of the equations has no solution; the two lines are parallel.</span>

levacccp [35]

Answer:

t=(v-u)/a

Step-by-step explanation:

The equation we start with is v=u+at and we need to isolate t.

First subtract u from both sides

v-u=at

Now just divide both sides by a

(v-u)/a=t or t=(v-u)/a
