Solving for 3 variables questions :o
help! Solve the system by elimination 1: x+5y4z=10, 2xy+5z=9, 2x10y5z=0 .
2. Solve the system by substitution: 2xy+z=4, z=5, 2x+3yz=10.
3. A food store makes a 11–pound mixture of peanuts, almonds, and raisins. The cost of peanuts is $1.50 per pound, almonds cost $3.00 per pound, and raisins cost $1.50 per pound. The mixture calls for twice as many peanuts as almonds. The total cost of the mixture is $21.00. How much of each ingredient did the store use?

6 lbs of peanuts, 3 lbs of almonds, 2 lbs of raisin. 6+3+2=11 6(1.5)+3(3)+2(1.5)=21 and 6=3*2 I misunderstood the english thats all haha. it was not y=2x, it's x=2y...
