Answer 1

plz i need help

Answer 2

i did not put the answers up because i need someone to show me how

Answer 3

you have

x + y = 6
x = y + 2

labeling them as eq A and B we get

x + y = 6 ----->A
x = y + 2------>B

putting value if x from eq B in A we get

y+2+y = 6

now from her find y

as you find y put that value of y in eq B to get x

thats it

Answer 4

so i would do for the next one x+y+a?

Answer 5

where is x+y+a ??
