1. 4.9 ÷ 7 =< br /> < br />
2. 3.6 ÷ 9 =< br /> < br />
3. 2.4 ÷ 8 =< br /> < br />
4. 6.48 ÷ 4 =< br /> < br />
5. 3.01 ÷ 7 =< br /> < br />
6. 4.26 ÷ 3 =

the correct answer

Y = 2x + 5
x + 2y = 15

    x + 2(2x + 5) = 15
x + 2(2x) + 2(5) = 15
      x + 4x + 10 = 15
            5x + 10 = 15
                  - 10 - 10
                     5x = 5
                      5     5
                       x = 1
y = 2(1) + 5
y = 2 + 5
y = 7
(x, y) = (1, 7)
