Weegy: 2x - y = 5
2y + x = 8
From the second equation:
x = 8 - 2y
Substitute that into the first equation:
2(8 - 2y) - y = 5
16 - 4y - y = 5
16 - 5 = 4y + y
11 = 5y
y = 11/5
y = 2.2
x = 8 - 2*2.2
x = 8 - 4.4
x = [ 3.6

Find the equation of the line that passes through (5,0) and has a slope of -2/3 (Points : 5)
y = -2/3x - 10/3
3y - 2x = 10
2x + 3y = 10
y = -2/3x + 5
Weegy: The equation of the line that passes through (5,0) and has a slope of -2/3 is y=-2/3x+10/3
User: 4x^3*x^12
Weegy: x^3 + 9x^2 +18x -10
User: Multiply 4x^3*2x^12
Weegy: If you mean (4x^3) (2x^12) then the result is 8x^15. You multiply the coefficients 4 and 2 and add the exponents 3 and 12.
