2) no change to the graphs

3) x = 1.47,  y = 4.71

coordinates at intersection = (1.47, 4.71)

Step-by-step explanation:

4x + 3y = 20

3x - 2y = -5

2) Declan's way:

8x + 6y = 40

9x - 6y = -15

No change in graphs

4x + 3y = 20,   3y = 20 - 4x   multiply by 2:  6y = 40 - 8x

3x - 2y = -5,     2y = 3x + 5     multiply by 3:  6y = 9x + 15

then:

40 - 8x = 9x + 15

simplify:

add 8x to each side:

17x + 15 = 40

subtract 15 from each side:

17x = 25

x = 1.47

3y = 20 - 4x

substitute for x:

3y = 20 - 4(1.47)

reduce:

3y = 14.12

y = 4.71
