PLEASE HELP ASAP 35 POINTS!!

Mathematics
1 answer:
OLga [1]4 years ago
4 0

Answer:

-1

Step-by-step explanation:

4x+5y=7

3x-2y= -12

To get the opposite coefficient, we multiply by -1

-1(4x+5y=7 )

-4x-5y = -7

-1*(3x-2y= -12)

-3x +2y = 12

Both equations now have the opposite coefficients on both x and y.

Work out b(4½-3⅔)+1⅔​
Zolol [24]

Answer:

2 \frac{1}{2}

Step-by-step explanation:

Change the mixed numbers to improper fractions

(\frac{9}{2} - \frac{11}{3} ) + \frac{5}{3} ← the LCM of 2 and 3 is 6

= \frac{9(3)}{2(3)} - \frac{11(2)}{3(2)} + \frac{5(2)}{3(2)}

= \frac{27}{6} - \frac{22}{6} + \frac{10}{6}

= \frac{5}{6} + \frac{10}{6}

= \frac{15}{6}

= \frac{5}{2}

= 2 \frac{1}{2}
