Answer:
(6,-7)
Step-by-step explanation:
subtract them:
-8x - 5y = -13
-4x - 5y = 11
you get
-4x = -24
so x = 6
plug x into the second equation:
-24 - 5y = 11
-5y = 35
y = -7
so your solution is (6,-7).
Answer:
17
Step-by-step explanation:
<span>Simplifying
4x + 5y = 11
Solving
4x + 5y = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
4x + 5y + -5y = 11 + -5y
Combine like terms: 5y + -5y = 0
4x + 0 = 11 + -5y
4x = 11 + -5y
Divide each side by '4'.
x = 2.75 + -1.25y
Simplifying
x = 2.75 + -1.25y</span>
