2x+8y=3 and 4x-3y=2 value of x and y.. plzz help me

lesya692 [45]

Answer:

Set a system of equations:

$\left \{ {{2x+8y=3} \atop {4x-3y=2}} \right.$

Multiply the whole upper equation by 2 and the whole bottom equation by 1 so their x-value equals:

$\left \{ {{2(2)x+8(2)y=3(2)} \atop {4(1)x-3(1)y=2(1)}} \right.\\\\=\left \{ {{4x+16y=6} \atop {4x-3y=2}} \right.$

Subtract the upper equation by the bottom equation & solve for y:

$(4x-4x)+(16y-(-3y))=6-2\\\\19y=4\\\\y=\frac{4}{19}$

Substitute in the y-value to a equation to find x:

$2x+8y=3\\\\2x+8(\frac{4}{19} )=3\\\\2x=3-\frac{32}{19} =\frac{57}{19} -\frac{32}{19} =\frac{25}{19} \\\\x=\frac{\frac{25}{19}}{2} =\frac{25}{19}*\frac{1}{2} =\frac{25}{38}$

Therefore, the answer would be:

$\left \{ {{y=\frac{4}{19} } \atop {x=\frac{25}{38} }} \right.$

Multiply or divide as indicated. 2 x • 3 x 2

VikaD [51]

2x (Multiplied by) 6

You cannot combine 2x and 6 because x is an unknown variable that is attached to a coefficient. Hope this helps!
