Step-by-step explanation:
Question 3: (4, -3)
Solving through elimination: Multiply the first equation by -3.
-3x+6y=-30
3x-5y = 27
Add. The x drops out.
y= -3
Substitute -3 in for y.
x-2y=10
x-2(-3)=10
x+6=10
x=4
Question 4: (2,5)
Solve through elimination: Multiply the second equation with 3.
[tex]\frac{3}{2} x+y=8[/tex]
[tex]\frac{9}{4} x-y=-\frac{1}{2}[/tex]
3/2= 6/4
15/4x=7.5
x=2
3/2 (2) + y = 8
3+ y =8
y=5
Question 5: (6,4)
Use your graph to graph.
[tex]y=-\frac{1}{3} x+6[/tex]
Slope of -1/3
Y-intercept of 6 (0,6)
X-intercept of 18 (18,0)
[tex]y=\frac{3}{2} x-5[/tex]
Slope of 3/2
Y-intercept of -5 (0,-5)
X-intercept of [tex]\frac{10}{3}[/tex] ([tex]\frac{10}{3}[/tex],0)
Question 6: (5, -7)
[tex]Ax+2By=-41[/tex]
[tex]4Ax-By=88[/tex]
[tex]3A+2B(4)=-41[/tex]
[tex]4A(3)-B(4)=88[/tex]
Solve by substitution:
