4x+3y=18.....(1) 3x+2y=5.....(2) write new equations by multiplying equation (1) by 3 and equation (2) by 4

desaishazi72: y= 2 and x= 3

srushtiii: can you explain in detail

desaishazi72: 4x+3y=18 eq 1 and. 3x + 2y = 5 eq. 2 . multiply eq 1 by 3 and eq 2 by 4.. 12x+ 9y= 54 eq 3 and 12x + 8y = 20 eq. 4 . Subtract eq 3 and eq 4 .... 17 y = 34 y = 17÷ 34 = 2 .... and put y= 2 in eq 1 ... 4x +3y = 18 .. 4x + 3×2 = 18 ... 4x + 6 = 18 ... 4x = 18 - 6 ... 4x = 12 .. x= 12÷ 4..... x = 3

srushtiii: Thank you

Answer:

THE NEW EQUATIONS FORMED ARE 12x + 9y = 54 AND 12x + 8y = 20.

Step-by-step explanation:

BY MULTIPLYING EQUATION {1} BY 3 ,

3[4x + 3y = 18] = 12x + 9y = 54.

BY MULTIPLYING EQUATION {2} BY 4,

4[3x + 2y = 5] = 12x + 8y = 20.

hope it helps..

please mark as brainliest..
