Step-by-step explanation:
2x - y = 11 -----(1)
x + 3y = -5 ------(2)
By
eliminating "y"
multiple equation 1 by 3 and equation 2 by 1
3×2x - 3y = 3×11
6x - 3y = 33 -----(3)
x + 3y = -5 ------(2)
add eqn (3) and eqn(2)
7x + 0 = 28
7x/7 = 28/7
x = 4
I hope this will help you, good luck!!!
A would be 12. If your sister is 6 years older than your brother your brother is 4
if your brother is 1/3 your age 4 times 3 you are 12
Answer:
y = -1/2x + 4
Step-by-step explanation:
I got -1/2x because for every 2 spaces, the line goes down 1 (rise/run)
I got +4 because 4 is where x = 0, or the y intercept
Answer:
f(x)=-
x+9
Step-by-step explanation:
Use the slope formula and slope intercept formula form y=mx + b to find the equation
