Answer:
a) 11
b) 9
Step-by-step explanation:
a) x=4 y=3
2x+y
2(4)+(3)
8+3
=11
b) a=-2 b=5
a^2+b
(-2)^2+(5)
4+5
=9

Answer: y=7,x=3
Steps:
y = 2x + 1
3x + y = 16
Substitute y = 2x + 1
3x + 2x + 1 = 16
Simplify
5x+1=16
Isolate x for 5x + 1 = 16: x = 3
For y = 2x + 1
Substitute x = 3
y = 2 · 3 + 1
Simplify
y = 7
The solutions to the system of equations are:
y = 7, x = 3
