Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = x - 16
5y = 2x - 56
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em>: 5(x - 16) = 2x - 56
- Distribute 5: 5x - 80 = 2x - 56
- [Subtraction Property of Equality] Subtract 2x on both sides: 3x - 80 = -56
- [Addition Property of Equality] Add 80 on both sides: 3x = 24
- [Division Property of Equality] Divide 3 on both sides: x = 8
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x - 16
- Substitute in <em>x</em>: y = 8 - 16
- Subtract: y = -8
a, b y c, d son iguales entre sí porque a es similar ab y si miras las líneas más de cerca, puedes ver que son iguales entre sí. Que tengas un buen día ... lo siento si no hablas español. :D
Answer:

Step-by-step explanation:
Answer:
31.8
Step-by-step explanation:
190.8/6
6 goes into 190.8 = 31 times
That equals 186.
You have a left over of 4.8
4.8 of 6 is 0.8
Getting your answer of 31.8
Answer:
40
Step-by-step explanation:
90 + 4x - 8 + 4x + 2 = 180
= 8x = 96
= x = 12
m < a = 4(12)-8 = 40
