Answer:
2561.2785
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
a
=
−
2
,
b
=
5
a
=
-
2
,
b
=
5
T
Step 1: Add the two equations.
Step 2: Solve for x.
Step 3: To find the y-value, substitute in 3 for x in one of the equations.
Step 4: Solve for y.
Step 5: Identify the solution as an ordered pair.
What if adding or subtracting does not eliminate a variable? Example. 3x – y = 8. x + 2y = 5.
