What's the answer too 7x+4y=14 ; y=6x-12 using elimination
2 answers:
Answer:
x = 2
y = 0
Step-by-step explanation:
To solve by elimination, you have to first change the equations so that you can cancel out one variable.
Change the second one.
4y = 24x - 48
Subtract them:
7x = -24x + 62
31x = 62
x = 2
y = 0
7x+4y=14
y=6x-12
Reorder:
7x+4y=14
-6x+y=-12
Multiply bottom one by 4:
7x+4y=14
4(-6x+y=-12)
=>
7x+4y=14
-24x+4y=-48
Combine/Eliminate:
-17x=-34
/-17 /-17
x=2
Plug x back in to one of the equations:
y=6(2)-12=12-12=0
Answer:
x=2, y=0

Answer:
3; 6; 9; 12; 15; 18;
Step-by-step explanation:
Multiples of 3:
3*1=3
3*2=6
3*3=9
3*4=12
3*5=15
3*6=18
w = p(y - z)
divide p on both sides

Subtract y on both sides

Divide -1 on both sides
