<span>The most accurate answer is Sarah's with 8,494.84 cm2. While Kevin's answer is accurate if you're using 3.14 for pi, pi is an infinite number and does not end at the 2 decimals he used.</span>
6x + 0.8 = 1.4....subtraction property .... subtract 0.8 from both sides
6x = 1.4 - 0.8 ...simplify
6x = 0.6 ... division property ... divide both sides by 6
x = 0.6/6 ...simplify
x = 0.1
Answer:
x=7
y=-1
Step-by-step explanation:
When the two equations are solved together, they form simultaneous equations.
x+y=6
x-y=8
Let us use the elimination method. if we add the two equations, we eliminate y.
2x=14
x=7
Let us substitute for the value of x obtained above.
x-y=8
7-y=8
y=7-8
y=-1
