7x + 2y = 48

7x + (2x3) =48
7x + 6 = 48
7x = 48 - 6
7x = 42

--> x = 6

Plug in 3 for y.
7x+2(3)=48

Multiply
7x+6=48

Subtract 6

7x=42

Divide by 7

x=6

2x + y = 15 x + y = 10​
Artyom0805 [142]

Answer:

2x+y=15x+y=10

Consider the first equation. Subtract 15x from both sides.

2x+y−15x=y

Combine 2x and −15x to get −13x.

−13x+y=y

Subtract y from both sides.

−13x+y−y=0

Combine y and −y to get 0.

−13x=0

Divide both sides by −13. Zero divided by any non-zero number gives zero.

x=0

Consider the second equation. Insert the known values of variables into the equation.

15×0+y=10

Multiply 15 and 0 to get 0.

0+y=10

Anything plus zero gives itself.
