Solve the system by elimination
x+3y=5
-x-y=-3
1 answer:
Answer:
x = 2 y= 1
Step-by-step explanation:
Solve the system by elimination by stacking the equations lining up the variables.
x + 3y = 5
-x - y = -3
Next, add each of the like terms.
x + 3y = 5
+ -x - y = -3
-----------------------
0x + 2y = 2
y = 1
Then substitute y = 1 into one of the equations.
x + 3(1) = 5
x + 3 = 5
x = 2

Answer:
5
Step-by-step explanation:
The solutions for eq 1 can be solved with these 2 equations (5x + 6 = 41) and -(5x + 6 = 41)....so there are 2 solutions
the solutions for eq 2 can be found with these 2 equations (2x + 13 = 28) and -(2x + 13 = 28)...so there are 2 solutions
so both absolute value equations have 2 solutions
Answer:
1/3x +2/3 = y
Step-by-step explanation:
y= 3x-2
To find the inverse, exchange x and y
x = 3y-2
And solve for y
x+2 = 3y-2+2
x+2 = 3y
Divide by 3
1/3(x+2) = 1/3(3y)
1/3x +2/3 = y
They aren’t like terms bc if the exponent
