Q. Solve using augmented matrices.5x−8y=−14x=10(_____, _____)
Substitute x value: First, let's substitute the value of x into the first equation to simplify it. Since x=10, we replace x in the equation 5x−8y=−14.Calculation: 5(10)−8y=−1450−8y=−14
Isolate y: Next, we need to isolate y. To do this, subtract 50 from both sides of the equation.Calculation: −8y=−14−50−8y=−64
Solve for y: Now, solve for y by dividing both sides by −8.Calculation: y=−64/−8y=8
