Step-by-step explanation:
-2x - 5y = 16___(1)
2x - 3y = -16___(2)
(1) + (2) ==> -2x -5y = 16
(+) <u>2x -3y = -16</u>
-8y = 0
y = 0/-8
y = 0
y=0 in (1)
(1)---> -2x-5y =16
-2x - 5(0) = 16
-2x - 0 = 16
-2x = 16
x = 16/-2
x = -8
x = -8 , y = 0
-5x + 2y = 11__(1) ; -3x + 4y = -13___(2)
multiply eqn(1) with 2
2 × (1) : -10x + 4y = 22___(3)
(3) - (2) :. -10x + 4y = 22
(-) <u>-3x </u><u>+</u><u> </u><u>4</u><u>y</u><u> </u><u>=</u><u> </u><u>-</u><u>1</u><u>3</u>
-7x = 35
x = 35/-7
x = -5
x=-5 in (1)
(1) : -5x + 2y = 11
-5(-5) + 2y = 11
25 + 2y = 11
2y = 11 - 25
2y = -14
y = -14/2
y = -7
x = -5 , y = -7
Answer:
5/6
Step-by-step explanation:
1/2 + 1/3 need a common denominator to add them up.
1/2 is the same as 3/6.
1/3 is the sane as 2/6.
3/6 + 2/6
Add the tops, but keep the same denominator.
3/6 + 2/6 = 5/6
5/6 cannot be simplified, so that's the answer. That's how you do it! Hope this helps!
To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
