Question If the first equation is multiplied by 3 and then the equations are added, the result is _____. 3x + y = 3 x – 3y = -2 10 x = 7 10 x = 11 8 x = 7.

Answer: if the first equation 3x – 3y = -2 is multiplication by 3 therefore, 3x – 3y = -2 multiplied by 3 :9x – 9y = -6 then the equations are added, 9x – 9y = -2 + 10x + 710x + 118x + 7 9x + 10x + 710x + 118x + 9y + 7 947x + 9y = 7 Log in to Reply
