If: x+y = 79 Then: y = 79-x
If: xy = 1288 Then: x(79-x) = 1288 and it follows that: 79x-x2-1288 = 0
Solving the above quadtratic equation gives x a value of 23 or 56
So the values are x = 23 and y = 56
Check: 23+56 = 79 and 23*56 = 1288
How do you solve 4y plus x equals 8
Equals anything... x is a variable. If that equation was set equal to zero then you could solve for x, but that is not what you have asked.
-2 plus 5 equals +3
Not enough information to solve
to solve ab=c+a for a:Divide both sides by b, so:a= (c+a)/b
It is not possible to solve a single linear equation in two variables.
1288
75 percent is equal to 0.75, so the expression would look like (0.75x) +8. But if you do not know what it equals to it is not an equation and you can not solve it.
That equation has no solution. There is no possible number that's equal to 18 more than itself.
A is 14

Px equals -0.6 plus 60x-1500
