Someone please help me❤️ Urgently with at least 1

Answer:

See step-by-step explanation

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.

$\frac{3}{2} x+y=8$

$\frac{9}{4} x-y=-\frac{1}{2}$

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.

$y=-\frac{1}{3} x+6$

Slope of -1/3

Y-intercept of 6 (0,6)

X-intercept of 18 (18,0)

$y=\frac{3}{2} x-5$

Slope of 3/2

Y-intercept of -5 (0,-5)

X-intercept of $\frac{10}{3}$ (

Question 6: (5, -7)

$Ax+2By=-41$

$4Ax-By=88$

$3A+2B(4)=-41$

$4A(3)-B(4)=88$

Solve by substitution:
