- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 4
y = -x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 4 = -x + 5
- Add <em>x</em> to both sides: 3x - 4 = 5
- Add 4 to both sides: 3x = 9
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -x + 5
- Substitute in <em>x</em>: y = -3 + 5
- Add: y = 2

Answer:
11, -4
Step-by-step explanation:
you have to do both of these top equations
a = 1
b = -7
c = -34 - 10 = -44
substitute these numbers into both equations to get x
x = 11 , -4
Answer:
29
Step-by-step explanation:
f(x)=4x+9
f(5)=4(5)+9
f(5)=20+9
f(x)=29
-1 (>=<) -7
-1 > -7
Hope this helped
