There is no visible symbol between 2x and 3y.
2x + 3y = 11Subract 2x from each side:3y = 11 - 2xDivide both sides by 3:y = 11/3 - (2/3)x
2x-11
How do you add 2x plus 3y equals 18 in 5x-y equals 11
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
Collect like terms: 2x + 3y + 3y - 5 - 6 2x + 6y - 11
(3,3)
Yes and it works out that x = 3 and y = 4
Solve for y.2x - 3y = 52x - 2x - 3y = -2x + 5-3y = -2x + 5-3y/-3 = -2x/-3 + 5/-3y = (2/3)x - 3/5Clearly you see that the slope is 2/3.
x + y = -2 2x + 3y = -9 You solve this by elimination - multiply both sides of first equation by 3, then subtract, solve for x, then substitute in any of the equations to solve for y 3x + 3y = -6 2x + 3y = -9 subtracting, x = 3 substituting into 1st equation, y = -2-3 = -5
2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
this can not be solved un less with another equation
2x-3y=13
