Answer:
Step-by-step explanation:
hello :
y= 5x + 9
y = -x +3
so : 5x+9 = -x+3
5x+x= 3-9
6x=-6
x=-6/6 = -1
5t+5=30
divide both sides by 5
t+1=6
minus 1 both sides
t=5
4x - 3y = 3...multiply by 4
5x - 4y = 3...multiply by -3
--------------
16x - 12y = 12 (result of multiplying by 4)
-15x + 12y = - 9 (result of multiplying by -3)
---------------add
x = 3
4x - 3y = 3
4(3) - 3y = 3
12 - 3y = 3
-3y = 3 - 12
-3y = - 9
y = -9/-3
y = 3
solution is (3,3).....and the x = 3
