Answer:
1/2x = 3*(27-12)
Step-by-step explanation:
Let x be the number
Is means equals
Difference means subtract
1/2x = 3*(27-12)
Equation 1 : x + y + z = 3.25
equation 2 : 12x + 2y + z = 9.50
equation 3 : 2x + 4y + 5z = ??
u would multiply equation 1 by -12.....take that result and add it to equation 2....this eliminates x.
u would multiply equation 3 by -6...take that result and add it to equation 2....this eliminates x
