**algebra ll**

so the answer is negative 5 right

**algebra ll**

the first equation of the system is mutiplied by 4, by what number would you mutiply the second equation to eliminate the y variable by adding? first: 2x+5y=16 second:8x - 4y =10 i got 2 0r 5 im not sure which one

**algebra ll**

the first equation of the system is mutiplied by 2,by what number would you mutiply the second equation to eliminate the x variable by adding. first:6x - 5y =21 4x+7y= 15 when i did the promblem i got 2 answers -3 or -2 im not sure which one

**math/algebrall**

drwls sorry its suppose to be written like this 1( -4, -10) ,(2,2) the one but when i did the equation agin i so confused that i got another answer it could also be (5,2)

**math/algebrall**

solve the system of equations:4x - 3y equals 14 and y equals -3x plus 4 i think its either 1(4,10) (2,2)
