Pachacha [2.7K]

for this, we need to divide the number of recruits that left over all recruits, and multiply by 100%: $\frac{30}{150} *100%= \frac{1}{5} *100%=20%$

so the number of trainees decreased by 20 %

Solve the system of linear equations by substitution x-y=-4 2x+y=4

mylen [45]

Answer:

Given:

x-y=-4

2x+y=4

Step-by-step explanation:

x-y=-4

2x+y=4

add both the equation, we get

⇒ x-y=-4

2x+y=4

⇒3x=-4+4

⇒3x=0

⇒x=0

∴ to find the value of y, put the value of x in any one equation

⇒x-y=-4

⇒0-y=-4

⇒-y=-4

⇒y=4

∴ x=0, y=4
