3x+4y=-3......(1)
5x+3y=6........(2)

So we multiply equation 1 by 5 and 2 by 3 and subtracting, we got

15x+20y=-15
15x+9y=18
(-) (-) (-)

11y=-33
y=-3

Putting y=-3 in equation 1, we have 3x-12=-3
3x=9
x=3

So x=3(Ans)
y=-3(Ans)

You know that 6x+3 equals 45 because the two sides are equal. So you first put the equation 6x+3=45. Then you use the subtraction property of equality and subtract 3 from both sides. This gives you 6x=42. Then you divide 6 from both sides to get you final answer, x=7
