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

Mathematics
1 answer:
Sidana [21]3 years ago
7 0

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    <em>x's cancel out so solve for y</em>

61y = -183

/61      /61

y = -3                 <em> insert y into either equation and solve for x</em>

<em />

<em>4(-3) -3x=-15</em>

<em>x = 1</em>

The equation of the line is y = -11x + 232

<h3>How to determine the equation?</h3>

The given parameters are:

Slope (m)= -11

Point (x1, y1) = (31, -109)

The linear equation is then calculated as:

y = m(x - x1) + y1

This gives

y = -11(x - 31) - 109

Evaluate the product

y = -11x + 341 - 109

Evaluate the like terms

y = -11x + 232

Hence, the equation of the line is y = -11x + 232
