Question

solvefor X &Y
x-y=2
3x + 2y = 16​

Answer 1

Answer:

x =2+y

3(2+y)+2y=16

6+3y+2y=16

6+5y=16

y=10/5

y=2

Answer 2

Answer:

Step-by-step explanation:

x−y=2;3x+2y=16

Step: Solvex−y=2for x:

x−y+y=2+y(Add y to both sides)

x=y+2

Step: Substitutey+2forxin3x+2y=16:

3x+2y=16

3(y+2)+2y=16

5y+6=16(Simplify both sides of the equation)

5y+6+−6=16+−6(Add -6 to both sides)

5y=10

5y

5

=

10

5

(Divide both sides by 5)

y=2

Step: Substitute2foryinx=y+2:

x=y+2

x=2+2

x=4(Simplify both sides of the equation)
