Q. Solve using elimination.5x+3y=−3−8x−3y=−6(_____, _____)
Write Equations: Write down the system of equations to be solved using elimination.5x+3y=−3−8x−3y=−6
Add Equations: Add the two equations together to eliminate the y variable.(5x+3y)+(–8x−3y)=–3+(–6)
Find x: Perform the addition to find the value of x.5x−8x+3y−3y=−3−6−3x=−9
Solve for x: Solve for x by dividing both sides of the equation by -3").\(\newline\$-3x / -3 = -9 / -3\)\(\newline\)\(x = 3\)
Substitute \(x\): Substitute the value of \(x\) back into one of the original equations to solve for \(y\). We'll use the first equation: \(5x + 3y = -3\).\(\newline\)\(5(3) + 3y = -3\)
Simplify Equation: Perform the multiplication to simplify the equation. \(15 + 3y = -3\)
Subtract \(15\): Subtract \(15\) from both sides of the equation to solve for \(y\).\[3y = -3 - 15\]\[3y = -18\]
Divide for y: Divide both sides of the equation by \(3\) to find the value of y.\(\newline\)\(\frac{3y}{3} = \frac{-18}{3}\)\(\newline\)\(y = -6\)
