Solve each system of equations below. Then verify that your solution make each equation true.
A.
y= 5x-2
y= 2x+10

B.
x=-2y-1
2x+y=-20

first one is (4,18) Second one is (-13, 6)

Step-by-step explanation: To verify the solution, plug in your x and y values in order to come up with the equation/solution.

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
