Find the solution to the system of equations

The solution is where the two lines intersect, because that is the point that makes both equations true.  You can do this solely by looking at the graph - we can see that the intersection point is (-2, -2), and so that is your answer.

a - base

b - exponent

so,

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
