-2x+15y=24 2x+9y=24, what is the value of x and y

kaheart [24]

Eliminate x's by adding te 2 equations

add them

-2x+15y=24
2x+9y=24 +
0x+24y=48

24y=48
divide both sides by 24
y=2

sub back

2x+9y=24
2x+9(2)=24
2x+18=24
minus 18 both sides
2x=6
divide 2
x=3

x=3
y=2

Rainbow [258]

Answer:

$\large\boxed{a.\ -30}$

Step-by-step explanation:

$\dfrac{y}{3}+8=-2\qquad\text{subtract 8 from both sides}\\\\\dfrac{y}{3}+8-8=-2-8\\\\\dfrac{y}{3}=-10\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{y}{3\!\!\!\!\diagup_1}=(3)(-10)\\\\y=-30$
