if i am solving a linear combanation nd it is y=-2+5 and 2x+7y
To solve a linear combination, we need to find the values of x and y that satisfy the given equations.
In this case, the equations are:
Equation 1: y = -2 + 5
Equation 2: 2x + 7y = ?
Let's start with Equation 1:
y = -2 + 5
Simplifying, we get:
y = 3
Now, let's move on to Equation 2:
2x + 7y = ?
Since we already know that y = 3, we can substitute it into the equation:
2x + 7(3) = ?
Simplifying further, we have:
2x + 21 = ?
To solve for x, we need to know the value on the right side of the equation. If you provide that value, we can proceed to find the solution for x.
