Answer:
Step-by-step explanation:
If you know that x = y - 4, you can plug that value into the equation 2x + 3y = 12 for x. This would look like:
2(y - 4) + 3y = 12
Simplify:
2y - 8 + 3y = 12
5y - 8 = 12
add 8 to both sides
5y = 20
divide both sides by 5
y = 4
Now, substitute y = 4 back into the equation x = y - 4:
x = 4 - 4
and simplify:
x = 0
This means that the answer is x = 0 and y = 4.
Step-by-step explanation:
or, 3(5-p)-2(5+p)=3(p+1)
or, 15-3p-10-2p=3p+3
or, 5-5p=3p+3
or, 5-3=3p+5p
or, 2=8p
or, 2/8=p
or, 1/4=p
