Where y=5x-7 and -3x-2y=-12 Write your answer as x,y

Mariulka [41]

Answer:

(x,y) = (2,3)

Step-by-step explanation:

y=5x-7 (i)

-3x-2y= -12

-(3x+2y)= -12

3x+2y= 12 (ii)

By putting the value of y from (i) in (ii)

3x+2(5x-7)=12

3x+10x-14=12

13x=12+14

13x= 26

x = $\frac{26}{13}$

x= 2

By putting the value of x in (i)

y= 5(2)-7

y= 10-7

y= 3

(x,y) = (2,3)

Step-by-step explanation:

Step 1: Define

14x + 18 + x = -112(x + 36) + 13

Step 2: Solve for x

Distribute -112: 14x + 18 + x = -112x - 4032 + 13
Combine like terms: 15x + 18 = -112x - 4019
Add 112x on both sides; 127x + 18 = -4019
Isolate x term: 127x = -4037
Isolate x: x = -4037/127

I need to know how to make it in its simplest form

Mrrafil [7]

Multiply denominator by whole number then add that number to the nominator. Which would be 5 times 1 plus 3. SO 5+3 IS 8 and you keep the denominator so the first one is 8/5
