Answer:
Step-by-step explanation:
y = x² + 3 x - 5 and x + y = -10 are the system of equations that do not have a real solution.
When the two equations are graphed and if they do not intersect, then there are no real solutions for the system of equations.
The value of "a" is 4
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
The above expression involves variables and constants
A variable is a symbol that represents an unknown number
Here the variable is "a"
Constants are fixed numbers like 1, 2 etc
<em><u>From given expression:</u></em>
Move the varibale "2a" from right side to left side of equation
When, 2a is moved from R.H.S to L.H.S, it becomes -2a
Now move the constant -2 from left side to right side of equation
Similarly, when -2 is moved from L.H.S to R.H.S, it becomes +2
Now add the variables on left side of equation
Now add the constants on right side of equation
Cancel the negative sign on both sides of equation
Thus the value of "a" is 4
