4x + 3y + 3 = 4 ----> 4x = 1 - 3y ----> x = 0.25 - 0.75y ----> 3y = 1 - 4x ----> y = (1/3) - (4/3)x
4x + 3y +3 = 4, however, if the values of x and y are not defined in the question, you cannot go any further to simplify this problem.
It is not possible to solve a single linear equation in two variables.
a) 4x+13y=40 b) 4x+3y=-40c) multiply b per(-1)=-4x-3y-40d) sum a and c: 4x+13y-4x-3y=40-(-40)=>10y=80 => y=8to find x replace y per its value in a or b and get x=-16
3y +3y = 6y
y = 8
-x+3y+6x-6y=5x-3y
The equation for 3y + 3y = -1 is 3y + 3y = -1.
That depends on what the value of x is.
That would depend on the plus or minus value of 3y or maybe an equality is missing none of which have been given.
it is equal to 6y plus y
If y + 3y + 10 = 70, then 4y + 10 = 70, and 4y = 60. We then find that y = 60/4 = 15.
If you mean y = 8 then the value of 3y+7 is 24+7 = 31
If you mean: 3y = 19+5 then the value of y is 8
Technically, the answer is probably YES, but it is a tautology and, therefore, adds no value.
2x-3y = 4 x+4y = -9 => x = -9-4y Substitute x = -9-4y into the top equation: 2(-9-4y)-3y = 4 -18-8y-3y = 4 -8y-3y = 4+18 -11y = 22 Divide both sides by -11 to find the value of y: y = -2 Substitute the value of y into the original equations to find the value of x: Therefore: x = -1 and y = -2 Remember that the product of a minus times a minus is equal to a plus when working out the original equations,
Yes.
Collecting like terms they are equal to: 2x+6y
Since x and y can get smaller and smaller without a limit, there is no minimum for the value of 3x+3y.
8y - 38
