Answer: (5,2)
Step-by-step explanation:
Given equations: 
Divide 2 on both sides of equation (1) and 4 on the both sides of equation (2), we get
Adding equation (3) and (4), we get
Substitute x=5 in equation (4), we get
Hence, the solution of the both equations is (5,2).
2x-15=3(x-15)
2x-15=3x-45
2x+30=3x
30=x
Let's check this work!
2(30)-15=3(30-15)
60-15=3(15)
45=45
She worked 45 hours each week
*the reason it is 2x-15 and not 15+2x is because "more than" is considered a "turn around word" meaning it is the opposite
I think it is:
A = 9y = 3yx
A = 9y = 3y (3)
A = 9y = 9y
A = 9y
A/9 = y?
a) f(4) = 3*4 - 4
= 8
b) h(-3) = 5 - ( - 3)
= 5 + 3 = 8
c) h(4) - f(-5) = 1 + ( -19)
= -18
have a nice day <3
