5x + 10y = 18

x = y - 6, replace x in the first equation we get:

5(y - 6) + 10y = 18

so, the result of substituting y - 6 in for x in the first equation is 5y - 30 + 10y = 18

x = y - 6, replace x in the first equation we get:

5(y - 6) + 10y = 18

so, the result of substituting y - 6 in for x in the first equation is 5y - 30 + 10y = 18

The line that passes through (-1, -3) and (2, 1) **Weegy:** The line that passes through (-1, -3) and (2, 1) is y = 4/3x - 5/3. **User:** 3x + 2y = 4
2x - y = 5
This system of equations
has no solution,
has one solution,
is coincident, **Weegy:** 3x + 2y = 4 2x - y = 5 This system of equations has one solution.
***Solve the following system:
{3 x+2 y = 4 | (equation 1)
2 x-y = 5 | (equation 2)
Subtract 2/3 ? (equation 1) from equation 2:
{3 x+2 y = 4 | (equation 1)
0 x-(7 y)/3 = [ 7/3 | (equation 2)
Multiply equation 2 by 3/7:
{3 x+2 y = 4 | (equation 1)
0 x-y = 1 | (equation 2)
Multiply equation 2 by -1:
{3 x+2 y = 4 | (equation 1)
0 x+y = -1 | (equation 2)
Subtract 2 ? (equation 2) from equation 1:
{3 x+0 y = 6 | (equation 1)
0 x+y = -1 | (equation 2)
Divide equation 1 by 3:
{x+0 y = 2 | (equation 1)
0 x+y = -1 | (equation 2)
