Question

Solve the system of equations. 7y + 10.x = -11 4y - 3x = -15

Answer 1

Answer:

x= 1

y= -3

Step-by-step explanation:

multiply them to get common factor for y or x:

3(7y+10x=-11)

10(4y-3x=-15)

21y+30x=-33

40y-30x=-150    x's cancel out so solve for y

61y = -183

/61      /61

y = -3                 insert y into either equation and solve for x

4(-3) -3x=-15

x = 1
