Question

Pls help need it ASAP the answer is not x=3, y=3

Answer 1

Answer:

x=4 and  y=1

Step-by-step explanation:

4x-y=15

2x+y=9

6x=24

x=24/6

x=4

4x-y=15

4(4)-y=15

16-y=15

-y=15-16

-y=-1 Divide both sides by -1

y=1

Answer 2

Answer:

x = 4 and y = 1

Step-by-step explanation:

4x - y = 15

2x + y = 9

Isolate x --

4x - y = 15 (add y to both sides)

4x = 15 + y (divide both sides by 4)

$\frac{4x}{4} =\frac{15}{4} +\frac{y}{4}$ (Simplify)

x = $\frac{15 + y}{4}$

Substitute x = 15 + y/ 4 in the other equation

2 * 15 + y/ 4 + y = 9 (simplify)

15 + 3y/ 2 = 9 (simplify)

y = 1 and x = 4
