Answer: the two numbers are 6 and 10
Step-by-step explanation:
Answer:
X=-14.5 Y=3.2
Step-by-step explanation:
5x-13=5y+7x
subtract 7x from both sides
-2x-13=5y
subtract 5y from both sides
-2x-5y-13=0
add 13 to both sides
-2x-5y=13
<u>SYSTEMS OF EQUATIONS NOW</u>
4x+15y=-10
-2x-5y=13
multiply the second equation by 3
4x+15y=-10
-6x-15y=39
add the equations together to get:
-2x=29
divide both by -2
x=-14.5
Substitute x into one equation
4(-14.5)+15y=-10
-58+15y=-10
add 58 to both sides
15y=48
divide both sides by 15
y=3.2
<em>CHECK YOUR WORK</em>
4(-14.5)+15(3.2)=-10
-58+48=-10
-10=-10
