Answer:
a set of two or more equations, each containing two or more variables whose values can simultaneously satisfy both or all the equations in the set, the number of variables being equal to or less than the number of equations in the set.
Step-by-step explanation:
It works because of two properties of equations: Multiplying (or dividing) the expression on each side by the same number does not alter the equation. Adding two equations produces another valid equation: e.g. 2x = x + 10 (x = 10) and x − 3 = 7 (x also = 10).
What i did is that i did $1.50 time 8 = $12.00 and then do $30.00-12.00=$18.00
Answer:
uh take or add x plus the y then z =5
Step-by-step explanation:
Answer:
d
Step-by-step explanation:
an equation always shows that sum is equal
in this case 1825026 will subtract 17 and the remainder will be used to find A
Answer:
-10 because you do parenthesis first
