substitution let the value of y in the A) 1st equation be the value of y in the second equation
u kno sub method it means u put value of variable obatained from an eq into another eq......
sorry im new to all this algebra stuff lol
like check the secon eq......u have the eqn for x...... nd u can put that easily in 3x+5y+4
wow um ther's an = missing
opps b. {x=3y-1 3x+5y+4
i think it's 3x+5y = 4
omg i just did that ughh lol
so what about the third problem how is it elimination?
coz it's not substitution.............it's kinda hard to isolate a variable(x/y) from either of the eqns........
oh okay thanks :)
