Answer: x-int = 10 and y-int = -12

Explanation:

Find x intercept:

To find x intercept set y = 0

3x - 2.5(0) = 30

3x = 30
x = 10

Find y-int:
Set x = 0

3(0) - 2.5y = 30
-2.5y = 30
y = 30/-2.5
y = -12

Answer:

x=0.833....y+10 (its a repeating 3)

y=1.2x−12

Step-by-step explanation:

for x is:

Add 2.5y to both sides.

3x−2.5y+2.5y=30+2.5y

3x=2.5y+30

Divide both sides by 3

x=0.833333y+10

for y is:

Add -3x to both sides.

3x−2.5y+−3x=30+−3x

−2.5y=−3x+30

Divide both sides by -2.5.

y=1.2x−12

hope this helps

Solve using elimination<br><br> 2x+5y=34<br> x+2y=14
Darina [25.2K]

2x + 5y = 34

x+2y = 14


Multiply the second equation by two to create like terms for one variable.

2(x+2y = 14)

2x + 4y = 28


2x + 5y = 34

2x + 4y = 28 -- Subtract.


y = 34.28 = 6


Solve for x


x + 2(6) = 14

x + 12 = 14

x = 2


Check:

2 + 2(6) = 14

2 + 12 = 14

14 = 14


Answer:

X = 2

Y = 6
