Q. Utilizar la calculadora gráfica de ALEKS para resolver el sistema de ecuaciones.6−0.9x=0.4y−y+0.2x=3.6Redondear a la centésima más cercana.(x,y)=(□,□)
Write System of Equations: Write down the system of equations.We have the following system of equations:6−0.9x=0.4y−y+0.2x=3.6
Solve for y: Solve the first equation for y.To find y in terms of x, we can rearrange the first equation:0.4y=6−0.9xy=(6−0.9x)/0.4y=15−(0.9x/0.4)y=15−2.25x
Substitute into Second Equation: Substitute the expression for y into the second equation.Now we substitute y=15−2.25x into the second equation:−(15−2.25x)+0.2x=3.6−15+2.25x+0.2x=3.62.25x+0.2x=3.6+152.45x=18.6
Solve for x: Solve for x.Divide both sides by 2.45 to find x:x=2.4518.6x=7.59 (rounded to the nearest hundredth)
Substitute for y: Substitute the value of x back into the expression for y.Now that we have x, we can find y:y=15−2.25(7.59)y=15−17.0775y=−2.08 (rounded to the nearest hundredth)
